I grew up in Iowa, and I live in a large Ohio city now. There are barely any LGBT folks in Iowa, even per capita, it’s just not normal or accepted there en mass. There was literally only one gay kid in my high school of 1500.
I move to Cleveland, then I meet more LGBT people than I have ever seen in my life, even having 4 lesbians in my workplace and one FTM.
But social media is probably the biggest driving factor behind the rise of so many LGBT people in the past decade.
Nothing you listed is liberal or left wing about LinkedIn, I mean I do fucking hate it too and you’re kind of forced to use it if you want to reach the upper echelons of corporate America and some companies will straight up just make you one without your permission which in turn will make your personal information available to anyone with a search engine.
