Part of the reason I started this instance was so that I, and anyone who chooses to join me, could talk freely about things that are not supposed to be talked about in Japan, on Twitter or otherwise.
Racism is a problem in Japan. It's a problem in the US. It's a problem in Europe. It's a problem everywhere.
A very unique set of circumstances occurs where people *from other countries* come to Japan and maintain racist beliefs. The same kinds of people who insist that racism doesn't exist (or if it does, that people like *me* are the ones who perpetuate it) take their beliefs from home, go abroad, sometimes to countries that do not have significant discussions or understandings concerning racism, and probably feel even freer to spout their hate than they did back home.
Here, no one will challenge them. Especially in a country like Japan, where "politics" aren't often discussed in public.
