"feelings yakuza" is an internet slang term referring to "those who turn their personal discomfort into a social evil and try to erase the
target completely". It has been used in proship/antiship discourse.
Typically, Americans will harass Japanese artists for being proship or pedophiles for what they draw. It's a concept that may be difficult to understand in Japan, where all fictional depictions are allowed, it'
s not good to insult someone's
work, and people are looked down upon for not being able to distinguish between fiction and
reality.
