I despise COG for being a gay larper but I do agree with the shit he pushes. Japan importing a bunch of third world muslims will only lead to then having to deal with the same shit Europe has been dealing with. More violence, more rapes and more foreigners trying to change the culture to their needs and not them assimilating to the existing culture.
It has happened in every country they have been imported into and it has been detrimental in every single case.
