Wrong. It seems to be popular with you though, the original demonstrators should have let themselves be attacked by the antifas without defending themselves?

Everyone has a right to defend themselves proportional to the way they are attacked. If verbally, then they should respond verbally. If physically, then they have to defend themselves physically.

But no one has a right to attack someone demonstrating non-violently. If they do, they are at fault, and the other party has a right to defend themselves.

Amazing that this basic rule actually has to be spelled out these days.
