It's interesting that the highest non-history subreddit is /r/european, which is a neo-nazi forum. Cool dataset at least.
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!
I thought I'd have to look at least a little bit harder than literally the first link I clicked, but: https://www.reddit.com/r/european/comments/4htthg/til_muslim...
Some choice comments include "sieg heil, NSB (Dutch fascists) was not wrong," comments about "negroid France," calls to poison halal food, issues they find with the survival of the white race due to the "blacks" and Muslims.
It is not a place for discussion of European culture. It is a vile cesspool of racists and hate.
Also the whole 18 being a symbol of neo-nazis.
What does 18 signify?
This isn't the first time I've asked cb18 why 18. Should I see another comment from them along similar lines, I'll ask again.
There's literally a stickied post about Holocaust denial right now.
