Watching stuff over at thedonald, it clicked that whether Trump or even the Democrats win in November, once the U.S. election is decided, there will be no reason for people to exercise restraint against antifa.
The only reason they can get away with their violent bullshit now is because regular people want the election to decide the next 4 years. But once that's decided, there's no reason to not respond and the cops won't protect them. Good time to be a supply teacher or an adjunct prof, as we could see a lot of long term sick days from them.
In Canada, they aren't as serious a thing, but once the ballots are cast and regular people don't have an election to lose, do they think people are going to forget about the arsons and the beatings? It looks very bad for them.
It's a few hundred people, less than a summer of murders in a single U.S. city like Chicago or Baltimore. Only difference in the case of a purge of antifa situation is that the people getting whacked would be white.
Military won't care. I wouldn't expect a revolution or even a cleanse, more like tidying-up. I think antifa in the U.S. may have started something they can't stop, but others will finish. Good time to not be in that country.
