OK, point made.
Let me rephrase: If you're not rioting, pillaging and overturning police vehicles the authorities shouldn't open up on you with Chainguns and flamethrowers ....
And if the authorities, or private citizens protecting themselves and their property DID open up with chainguns and flamethrowers, with no repercussions*, we likely wouldn't be discussing needing to make the antifa cowards a terrorist organization, because they'd be too afraid to loot in the first place.
Much of this violence happens because there are few or no repercussions. The authorities (and counter-protestors) are more likely to take violent action against KKK members doing nothing but holding signs. While the KKK is reprehensible, if they're being non-violent, ignore them. Antifa and others actually harming people are somehow given passes, and people who defend themselves against them are more likely to be jailed than the antifa members. Hit a KKK member just holding a sign, and you're given a medal. Defend yourself against an antifa goon trying to bash your head in with a bike lock, and prepare to be arrested in many jurisdictions.
*Hyperbole, yes, but more realistically, two to COM or a load of buckshot should be perfectly valid forms of defense.
