It's the WORST. I know toxic fandom has always been a thing, it just seems to have gotten both worse and broader in the last handful of years. The movement toward MORALIZING the ship wars has really been horrible to watch. It's not just "I don't like your ship and think you have bad taste" it's "your ship is immoral in some way and that makes you a bad person and that means I am righteously justified in hurting you in any way I can".
I could go on a REALLY long rant about it, haha.
