I dunno. It’s hard to unpick the racist/right wing stuff from the antiestablishment anger you saw in, say, the London 2012 riots. Which definitely weren’t triggered by right wing agitators. It’s the same disenfranchised youth kicking in the windows of foot locker either way. The underlying theme seems to be more about being angry at the state/police rather than any coherent right wing ideology.
Yes, but that's almost always the case. The underlying theme is almost always a paralell justifiable anger. We're not short of data, we've been scrutinising it closely since the second world war.
The only time a crowd is almost entirely racist is if there is a reaction from the oppressed, then the counter reaction will be much more densely ideologically racist.
Even successful elections for overtly racist parties are won by appealing to the existing, often unrelated anger.
Let's hope you're right and Ireland is the only country where this doesn't happen.
