It's the inevitable next step on the road of demonizing anyone who doesn't think, act, and vote the way you want them to. And both sides are guilty of doing it, it's just that the left has the whip hand right now because they can pass a lot of their bullshit by using positions that most decent people don't have particular issues with as a shield for the more outrageous crap (see gays being allowed to marry serving as a shield for troons strutting cock out in women's locker rooms.)
