Gatekeeping is necessary if you want to protect your hobby. Every anime or game with a healthy fandom actively filtered the antis.
They show up fast and will ruin things if you don’t push back.
What’s also concerning is the attempt to erase concepts entirely — tomboy erasure is real and I’ve seen it multiple times. Same thing with femboy erasure.
Antis can’t engage with media without forcing politics into it. It’s beyond them.
