I've never touched the series because I always thought it was too gross, so I feel nothing.
That said, isn't fucking stupid to remove shit like ninjas from media because of "racism," when the point is that ninjas are fucking cool and results in people being drawn to other aspects of east asian culture? I know I'm preaching to the choir here, but the things that globohomo are calling "racist" or "anti-asian," by proxy, are shit like shaolin monks, samurai warriors, martial arts, geishas, chinese dragons, kaiju fights, chakras & chi, ancient chinese secrets, koi ponds, and etc. You know, just about everything badass, admirable, and awe inspiring that you could relate to Asia (i.e. common asian-related stereotypes). Westerners are fucking addicted to the continent because of shit like this and have been for centuries, whether it's accurate or not. Ban that, and basically all you have left is Tiananmen Square, North Korea, designated shitting streets, and k-pop.
