every ship has its toxic shippers, but that doesn't necessarily make one ship superior to another. when it comes to yumihisu & erehisu, you could make solid arguments for either ship, as the story has enough material to support both. it all comes down to a matter of personal +
preference. that being said, i think it's unfair to call out all yumihisu shippers for something only a fraction of them do. some of you seem to forget that ymir is a huge part of historia's development, so talking about their relationship IS appreciating historia's character. +
not only that, but seeing such a natural and healthy wlw ship in fiction is not common, so it can be really comforting for people to see this representation in aot. i don't understand what is so difficult about letting people be happy and enjoy what they want to enjoy
