To summarise my point.
Seventh bullet said "I am too soft, a wet fart in fact, but I do appreciate that you can't turn the other cheek with people like the far-right. We need 'thugs' who aren't 'just as bad' as the fascists (as liberals like to say) but people who are better than them at spreading a message physically, politically."
I belive his point being that apposing violent people sometimes requires violence.
I disagreed with that because a) I don't think you need to in a functioning democracy and b) if you accept people who enjoy fighting in the street you run the risk of accepting people who simply like fighting and aren't that picky about who they fight.
My only experience of such an event was Welling, because happly things like that are rare - for me anyway.
