Full disclosure: as a Christian I believe the bible speaks against homosexuality (along with thousands of other sins) and that there are two genders. That being said, I am a firm believer that people should live how the please as long as they are not hurting anyone and if an adult wants to "change their gender" more power to them. I'll support your right to live how you want, and I hope they can respect my right to worship how I choose.
The other day I saw a commercial with a black "transwoman" talking about how when he was growing up he didn't see anyone that represented him. I almost started screaming at the TV. There is a very tiny amount of men who have gender dysphoria, and black men with gender dysphoria is an even smaller number. He was talking about how he wanted to make movies and I rolled my eyes because I am sure he will win an oscar someday by making some garbage movie that the critics will gush over.
Why do you think there seems to be an agenda to make it seem like LGBT people make up a large portion of the population? Of course anyone who asks this question gets told "gay people exist" or something about how heterosexuals shove their "heteronormative" lifestyle down everyone's throats. No point in responding to it because they will just screech louder if I say heterosexuality is the norm.
And of course with the representation comes the overhype like you see if there is a female, black, or hispanic person in a movie or TV Show. I can remember seeing articles about that one lady on Stranger Things who is a lesbian talking about how she was the best character in the whole series and to me that made no sense for a show paying homage to the 80s with a reformed jock and the nerdy girl, but gotta subvert expectations. Or the San Junipero episode of Black Mirror. The episode about ranking people via social media was a much better look at our society and raised some interesting questions but of course San Junipero was treated like the second coming of Citizen Kane.
So why do you think there is so much over-representation? I also saw a poll about LGBT being very high in younger groups but I have to believe at least some of that is due to being trendy and a lot of women who are married to men seem to love to say they are queer.
Like I said there are gay people who have the "don't bother me and I won't bother you" mentality. I'm mainly referring to the radical movement that considers it oppression if you don't enthusiastically celebrate and affirm their lifestyle.
I can tell you from personal experience in high school and pattern recognition :
For starters, you'll come across a disproportionate % of gay men in the arts. Music, dance, theater, etc. This was the case even when homosexuality was illegal. They just stayed in the closet. There was no "gay agenda to infiltrate". The brain development causes of homosexuality and made gay men more inclined for those interests.
This gives "media visibility" to people who have a totally skewed perception lf the % of homosexuals in the general population.
It made a feedback loop with the change from "we don't talk about that" to "it's okay, tolerance yay" to "CELEBRATE ME BIGOT".
Sprinkle Academia Grievance Studies and SJWs on top of that, and you get the current lunacy.
