This is something any of us can do anywhere.
Shunning sounds like faggy shit, but it works. It’s not violent, so muh optics for the retards who still believe in that.
Make being a pig, antifa, journalist, or other undesirable completely socially unacceptable in your circles. Their friends, their family, supporters, and enablers also get nothing.
When possible, loudly identify them for everyone around to hear, but do not otherwise harass them or interact with them.
Refuse to buy, sell, speak to, or otherwise do business with them for as long as you can get away with it.
The law may try to intervene to make you “bake the cake bigot” or stop the “verbal harassment.” But as we just saw in Ottowa, there are a lot more of us than there are of them, and cops can`t be everywhere. And feel free to lie, these scum aren`t people and are not due the consideration you would give to an ordinary human.
