Oh I know. The way things are going, especially with Trump's rhetoric, one has to be concerned.
If it's just his rhetoric then we're fine.
He's not telling his supporters to actively go out to assault, or harass opponents, or their supporters in turn. The last time I've seen him even supporting one of his own people in any kind of violent act, it was in self defense, and that was when a protestor had snuck into their rally and kept trying to start fights.
It's bad enough with democrats jumping on this "concentration camp" bandwagon and many more of them saying, never again. Like they're actually fighting against Nazis.
When the right goes bad, it's someone who's usually alone and certifiably insane. They kill who they can before they're taken down and that's it. But when the left commits their violence, they crowed into their little black block mobs and attack anyone indiscriminately.
So far, I've personally seen people, stabbed, beaten, and maced. Some of which were older women holding children, who were not even participating in any aspect of the event. They just happened to be nearby. At Charlottesville there was one trying to set people on fire.
How bad do you think this will be when over three hundred of them, like what happened at Berkley. Come out and begin to not only torch the city, but kill people without discretion?
All simply because they believe that they're the ones fighting some sort of oppressive, monster regime.
