So what changed in the 90s? Here's what changed...
In the mid-late 80s, AZT was approved as an AIDS drug, and suddenly we were able to start thinking of having AIDS as something other than an automatic death sentence. An ENTIRE GENERATION of LGBTQ people was lost in the 80s to early 90s. An entire generation.
What else changed? The Reagan/Bush regime ended. Reagan demonized the gay community and took the least action possible after the AIDs crisis broke and had a name. 8 years of Clinton meant baby steps of legislative progress, but so much more in terms of visibility and acceptance. Our leaders were no longer telling us that we were the enemy. Imagine that.
And as the above movies demonstrate, corporations jumped on the bandwagon because they discovered they could make money off our demographic. We were better educated, had decent paying jobs, and more expendible income. We became a capitalist debutante and they lined up as suitors for our dowery.
Then came the W years, and we had to fight to keep what we'd fought for in terms of social equality... but 9/11 sort of took the focus away from us as the preferred enemy of conservatives, replaced by Muslims and POC in general. And the corporations were still making bank, so they didn't turn on us all that much.
Then came the Obama years... *chef's kiss* Even after the dirty Prop 8 campaign in California, Barack the Constitutional scholar helped shepherd marriage equality into a winnable, codifying SCOTUS decision. God bless that man.
But then came Trump, and I'm not gonna go into that here. Let's just say that while corporations still love to take our money (I agree about the commercialized bloat of Pride Month), they're taking different marching orders when it comes to hiring and discrimination now.
This whole concept of "being told you're dirty and wrong" seems odd to you because, well, it's new for you. You haven't been facing it your whole life. Suddenly we're in culture wars with two actual sides. It's overkill, but maybe it's needed before we strike the right balance eventually. Peace and love to you and yours.
