Note: Possibly Mindkilling
In Ireland, antifa is pretty small, but seems to be closely associated with radical republicanism - which has a specific meaning in Irish politics: Sinn Féin and other more millitant nationalist groups, generally left-leaning (or appearing to be to gain popular working-class approval) and often anti-British.
This leads to the odd situation where antifa is closely correlated with nationalism.
I have found this most wonderful (if fairly lengthy) article, and thought you would enjoy having it brought to your attention.
It is so good, I think we should include it among the references in the "Politics is the Mind Killer" wiki page. But, before that, I submit it to you, and ask you: is there anything in this article that would warrant its exclusion from this site? I mean, besides the fact that it is about politics, and written by a notorious Social-democrat (And is that in itself grounds for exclusion?).
