3/5
Because I 'know' what it is to be gay, and I know what it is to be closeted - and I am old enough to remember when we were not allowed to be discussed in school - because i was in school at the time.
I know what it means to be a minority who is shunned for their very existence - whereby powerful or influential members of this sub-culture (teachers, priests etc) - can use - or could use - their influence to drive situations whereby the younger person or less experienced person is helpless or driven toward behaviour they may not really choose, if they're being super honest with themselves.
I know what it is like to have a manager single you out in a meeting and tell a joke about anal sex, and finish it with "as dfslkjbnltalrvlxdguh knows" - which, tbh, I can't remember the joke, and it was funny if I'm honest - but it was still... ya know?
Maybe you don't know? Again, that's not an accusation or anything negative. I'm not calling you ignorant or homophobic or bigoted (you'll not I've not done that in any previous replies either).
I'm gonna narrow that wall of text to one simple question:
Ok.
"What is the base role of having sex ?"
Ok, again, without reading past that at this point - my answer to that question is in an evolutionary / biological sense, for procreation - to pass the genes on from parent to child, one generation to the next. That's it's primary purpose (i.e. what it does on a base level).
So, to directly answer your question, is the above.
However - and please take LGBTQ+ people / situations out of this for a moment - sex is not just for procreation.
There are some who believe it should only be for that - usually for religious reasons which I will not get into and I don't have any real interest in debating the specifics here and there - suffice it to say, it's not all religious people and it's usually the 'fundamentalists' - in many countries - USA, UK, Kenya, Bolovia etc.
It is also fair to say, I think that those who are what we call 'conservative', tend to be 'against LGBTQ+'. Note please I said 'conservative' with a small C - I am not talking any specific party or ideology or left or right - just that those who tend to value traditions and the ways that have come before (and led us to where we are) are valuable and should be upkept.
This comes into direct conflict with 'progressives'. Progressive, in my mind, does not always mean 'good'. It means change - trying new things, altering ideas, changing how we do stuff - with the goal being to make things 'better' (socially, healthcare, economically, whatever sector you want).
Conservatism and progressivism butt heads regularly. Conservatism - absent of any bias - will say that LGBTQ is a minority issue, doesn't affect most people, it's not something to be encouraged and - I'm not trying to be silly here - basically it's a case of 'ignore it and it'll go away' or in some cases, 'supress it' (via various methods/means and in varying degrees of implementation - for example ISIS throw gay people - or those just accused of homosexual acts - off buildings. I apologise for the title of the video (it says Muslims rather than ISIS, and is a little vague there - it's a bit like saying "christians" or "white people" when they mean Jimmy Saville).
Now - they do not represent conservatives, conservatism, Conservatives (as in the part), "The Right" in general, or Muslims or an interpretation of Islam. They're just sick fucks.
However, as you can see, when left unchecked, there are elements in society who can and will attack and kill / torture / maim LGTBTQ+ people, either for the fun of it or because a booming voice told them to.
To combat this, we (progressives) are not trying to attack the religions or conservatism or conservatives - we are not trying to fight this directly. By this I mean, we're not throwing rogue imams who issue or haram fatwas (unlawful religious judgements) in response - instead, we try to educate by opening up to the world.
This is what LGBTQ+ education in schools is for and tries to do.
Forgive me, but I will make an assumption - you are well past senior school age - you're either in your 20s or above (and i think 30s, but that's just me heh).
What is educated now is not what you or I went through, when we had sex education.
Tbh I went to an independent school for most of my senior years (though went to a state college and stage junior school). Our sex education, at an all boys school, was having the biology teacher put on a video from what looked like the late 70s, about a boy and a girl on a bus. They were flirting, and we were told that the male and female may blush in response. We may feel "shy" ... and so on.
It went on about the - honestly, it's like a cliché - changes in the body and hair growing in 'strange places'.
That level of bullshit.
Mate, I don't know if you're aware, but both straight and LGBTQI+ people are having (or have access to) sex from 15/16+ fairly regularly, including use of drugs such as MDMA, cocaine and (for what it's worth) weed.
Not everyone, of course - but a fair portion.
And how useful was that? Not at all. The teacher than put a condom over a cucumber (which put in our minds images of sizes and measuring up which were of course not real!) and explained that when the male "releases his sperm, he receives a pleasurable sensation".
That was it.
My parents paid thousands for that school, and that was the sex education in 1994/1995.
Oh, we did genetics and stuff for GCSE, like, we knew what a sperm was doing (basically) but we had no clue what sex is/was.
It was something a 'male' and a 'female' 'did'. It was very clinical.
That't not sex, and that's not sexuality.
If you ever lament the amount of teenage pregnancies or STDs going around - it's not because of sex education, it's because half the kids think a blowjob will get you pregnant and the other half think that because you have a rash, you can't get any other STD.
The solution is more education - and from a LGBTQI+ point of view, access to people we can talk to (therapists, counselors etc) who we can speak with and ask questions in private / confidence.
Education on the subject doens't encourage it in people who are straight, u/wolfiasty. There is no danger of reading about how gay people live, and then 'contracting' or otherwise experimenting yourself - unless it's something you choose to do.
