"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.
