>/r/european, which is a neo-nazi forum

That's not an accurate characterization.

There is an element of that, but it is frequently pushed back against.

It's mostly people who are dismayed by this recent migrant madness and the resultant massive spike in horrible crimes.

It is ostensibly also just a place for discussion of european culture but attention to the migrant madness, and seeking political solutions for it dominates the conversation because the issue is so heavily censored elsewhere on reddit.

edit: And it's highly likely that the vast majority of occurences of the string 'nazi' in that sub are in the context of satirical postings like, Oh, you think borders should be secure and rapists should be prosecuted? You must be a nazi!
