I think these issues are pretty similar to one another as far as how they impact the person and makes the person feel in general. Yeah sure they are different but at the end guess what, goal achieved ya feel like shit because someone came around and said or did some shit.
I think a lot of it may come from a disconnect and a focus on ones self. You feel so bad and you feel like one gender hates or doesn't like you for whatever flaw you think you have or even actually have. So you become biased. How could the haters possibly understand anyways. You can't necessarily feel others pain so you assume yours is greater, your burden is the heavier burden of the two. You have a very intimate understanding of what makes you feel like shit vs a more vague of what makes the other person feels like shit. Because of this in-depth knowledge it gives you the illusion of proof that your issue is worse than the other persons.
Somewhere in all of that they miss the entire issue and it turns into a pissing contest of who has it the worst or hurts more. He(whoever) is hurting and She(whoever) is hurting. So like say I face a lot of crap with what makes me feel bad, I think that is an opportunity to help try to come to a better understanding of someone else. While there are differences, I think there are more similarities or simply enough to come to an understanding of one another. That said I don't know how to reach someone who is that swallowed up in their insecurities they are unable/refuse to see the others are in. Maybe point out like "hey man/woman I hurt too and I don't think it matters who hurts more because at the end of the day we both are hurting." Maybe from there something constructive could arise but :\ I'm not good with stuff like that so idk. I like to read sbp because while it is not good that some of the stuff happens it is good to try to understand what women may go through. I find myself learning new things and that x happens or y happens way more than I ever imagined.
Also there is stuff to learn that benefits me directly as I'm sure many have worked or are working through insecurities. I might be able to take a page out of their book and put it into mine. Initially when first visited Sbp I did so through a link because I was like :D I like small boobs....smallboobPROBLEMS hmmmmmm what problems could those possibly be. Yeah ik I was an ignorant fuck and still am in many regards, but it was eye opening (and not just for issues revolving around boobs) and nonetheless I was glad I followed the link.
TLDR they all suck suck shit. It doesn't matter who sucks more, everyone hurts at the end of the day. Use your experience with your own pain to help others as you may have a different perspective which could be just what you or the other person needs. This is a people thing because they get too self absorbed in their own insecurities that they can't see past them and recognize that others deal with crap too. Mindless babbling over.
