The gay pride parades originated in response to Stonewall, in order to counteract the popular perception of gay people as “child molesters” or “threats to society.” The very fact that the “gay panic defense” existed ever, for example, is a key testament to how society used to (and still does, to a degree) marginalize gay people by spreading all sorts of misinformation about gay people as “harassers” and criminals. They are meant to show visibility, for two purposes. One is so that people cannot re-marginalize gay people and send them back to the days of hate crimes and murders. The other is to help manage the teen suicide rate by letting kids know that it’s normal for someone to be gay, that they don’t need to shame themselves over it, despite what their family, friends, or culture may say.
No offense, but saying “I wish we could go back to the days when gay people were quiet and never showed themselves ever” is no different than saying “I wish we could go back to the days when black people weren’t so uppity and demanding civil rights” or “I wish we could go back to when women just accepted they couldn’t vote and didn’t make such a huge fuss about sexism.” A human right is a human right. A right to life is a right to life. A right to not be bullied or harassed or put down for one’s sexual orientation is a human right.
Unfortunately gay pride parades have been usurped by those who want to act ridiculous and scandalous. But that is not their purpose whatsoever. Gay pride parades are not about sex whatsoever. They are about one’s innate, immutable orientation and refusing to be harmed by others over it anymore.
