In my own experience, I find that the gay community is just like any other community. It depends on what angle you choose to look at it. There is a good and bad side to it.
From my own experience with groups I have been apart of, I will say there always seems to be the one loud person/s who makes it not so enjoyable for me. It starts to feel controlled by them, the people I may feel good around may start avoiding being involved in it, then the group slowly dies out because of it. This person is usually superficial, a bully and probably insecure himself. I will usually stay friends with the individuals I didn't mind speaking with. There are the good/bad people in these communities, I just stopped seeking out groups to make friends in. I have lost friends because someone didn't like me, so they got my own friends to turn their back on me because of malicious rumours they have spread about me - that really just means these people weren't my friends to begin with.
I did get ganged upon most gay guys in my smaller city when I came out. In high school I preferred to keep it private between friends, but a few gay guys in my school outed me and made cruel jokes about me to people in my school. They weren't supportive and were the only people who truly cared that I was gay in high school, making me feel uncomfortable.
A lot of media does sexualize or generalize us. Some things like "FKH8" exploits the LGBT community, along with oppressed communities - Although I am sure most people will agree upon that by now. I don't think tribes should define us either, but I do understand if that's just a way for people to find it easier to find their type in such a small group. I don't really have a full opinion over it, I just don't want to be defined as a twink because I am worth more than that.
Parades. Parades have such a mixed opinion, but I define a parade as a gathering to express yourself in a way that you're unable to in the daily life. I personally don't do parades, but that's just because they don't interest me at the moment.
To conclude all of this, if you think in a certain way there will be others who feel the same way too, to involve yourself with. A lot of people are uncomfortable with coming out so they act out, all in a form of insecurity. By truth, I will say only a small percentage of gay men I have associated with haven't been pleasant, but it would be just as bad for me to judge every gay guy because of that. This is just all my own experience.
