Explanation in Comments

These shippers are absolutely toxic, have death threatened the creator JUST BECAUSE HE DIDNT MAKE IT CANON IN THE END. And if you make a group where you hate this ship, they go in and complain because you hate it. They didn't even watch the anime, and there is a 90% chance they support those corny MHA tiktoks.
They are the reason that the MHA Fandom is in the worst fandoms videos.

AND IF YOU SAY YOU HATE IT/DONT SHIP IT, THEY CONSIDER YOU "A HOMOPHOBE" (One of these did this in one of my other bkdk hate posts, don't worry, their account is deleted now.)

I would write out a few methods to deal with them but I don’t want to get banned

Do they involve being assholes to them?

I was going to suggest stuff that breaks way too many laws but yeah sure
