The article opens with exactly that. It's not a mystery either. Biden never made more than a pro forma attempt to fulfill his campaign promises and is tacking hard right this election.
Weird how people flex their ignorance of how the American electoral system works.
Pull your head out of your ass and be pragmatic. Biden is an asshole and extremely problematic. But Trump will try to actively chip away at your rights at best, and put you in a camp at worst. That’s not hyperbole. I fully expect “undesirables” to be rounded up at some point if Trump somehow gets reelected. And if you don’t think Trump and his sycophants will lump non-heterosexuals in with “undesirables”, you’re a willfully ignorant simpleton.
