I think people buy standards, sold by media or whoever.
It´s irritating when some gays want to oblige others gays to have an erratic behavior, drinking so much, maintaining a "party animal" attitude and being sexually liberal. If the person likes it and if he can faces the consequences, it´s his life. But some persons prefer to live a calm life, some are religious, some dream with wedding. So, there isn´t a recipe for being gay.
The comment above made me think. Sometimes, it seems there is no gay community. I need to agree with that comment, partially, because, sometimes, I really see some isolated communities: the "Party Animals", the "Fashion/Make up bloggers/Youtubers", the "Fitness obsessed" and others.
There are stereotypes who are sold by media and the worst is that most of persons, gay and straight, buy them! For example, one of those stereotypes is that a gay necessarily needs to like some Music Divas like Britney Spears, Madonna and Cher. I liked Madonna in the past, I don´t know much about Cher´s work and I recognize there are some Britney´s songs that are catchy, but, as artist, I don´t think she is especially talented. I never bought her albums. Why am I obligated to like her just because I´m gay? Come on! It makes no sense. There are gays who like Heavy Metal, or Rock, or Indie, or Classical Music. Just because someone is gay he doesn´t need to like the current Pop Divas. But a part of the gay "community" buys this stereotype ... and reproduces it! Another stereotype is, just because I´m gay, I must be a Fashion expert. Once a person said: "- So, you are gay. Then, we need to talk. I want some Fashion advices". Why do people say things like that? I´m not a Fashion expert. I don´t know much about it. Why would I need to have all this knowledge about Fashion just because I´m gay? But it´s a portrait that is sold by media!
But, talking now about straight persons, I also think the straight "communities" (?) have difficulties to accept alternative lifestyles/personalities because they also buy those prefabricated ideas of an ideal life.
So, I don´t think it is not necessarily about the gay "community", I presume it´s all about stopping buying cliches.
