I am not an expert in any field relating to any of this by any means, but we can all agree that CSAM is unequivocally reprehensible. Thusly many people will have severe issues with anything that normalizes it even remotely. That would be my knee jerk response anyway.
The thing that sticks out in my mind right now is the steamed pizza buns (pizzaman) from 7-11 in Japan. That feels somewhat embarrassing to say because it’s just a convenience store snack… but I miss them constantly.
