It's one thing to be an asshole, it's quite another to subscribe to Nazi ideology.
Linus Torvalds, for example, used to be a raging asshole, but as far as I know he was just a dick to other people who had pissed him off. He wasn't advocating for genocide or stripping rights away from people or whatever.
This FRIGN guy seems like he might be a part of the latter group. If true, that makes him a very different kind of asshole, the kind we do not welcome into our communities.
