You guys are delusional if you deny the fact that anarchists are going there on Friday to stir up trouble. That's what they do. They should protest peacefully, but if they do violence, it should be an eye for an eye.
And "stirring up trouble" is wrong why exactly? Surely you can't be blind or stupid enough to think that the States violence is fully justified but that of individuals must be necessarily wrong if it comes into contact with power or property?
May as well add that I personally do not support insurrectionism.
