Didnt Yoshida himself once stated its just a different mentality? Like how JP players often want to try out everything while the western world does not do that thus those that are not interested in savage simply wont do it, while in JP some might still try it just because its content.

I also once heard from someone working with a jP company that it can be quite annoying because of their mentality of keeping once face. Instead of telling their opinion about a product or project they try talking around it which makes it harder.

In the end you have bad apples everywhere so I dont agree with the OP. Just because some clear rates in some contents are better does not make them better people. And others have already pointed out that they have offical black lists outside the game and Yoshida too once said in an interview that he is not telling much about his private life and family because he fears for their safety. (Yes from other JP players) And the person that said those death threats after the recent ultimate clear was posting this from seemingly an jp account too.
