Key word there is YET.
The SJW have taken from the playbook of Islam.
Your act that offended them isn’t an emotional affront, it is seen as a violent act, an act of “aggression”.
Repeatedly challenging or even questioning their beliefs and perceptions is then an act of aggression.
They then see themselves as having the right to act violently, from shouting people down to ripping up signs to threatening to burn down businesses.
After all, the other side won’t stop expressing contrary views or questioning underlying beliefs, and that’s an insult on SJW / Islam and must be responded to with threats of violence if not actual violence. But they have an obligation to try to convert you first.
