>>Mere words on a T-shirt are not sufficient justification for violence. Shame on these so-called "ultra-orthodox" for besmirching Judaism with their aggression.<<
I agree but only to a point.
If 50 people came into a neighborhood, knowing they weren't wanted there and all had the same shirts with a message that the neighborhood would be hostile to, what did they expect?
People can be patient but sometimes we have to think before doing things.
To be treated like human beings.
It is immoral to commit acts of violence against a fellow human being except as a last resort in defense of self, others, or nation. Attacking someone because of a slogan printed on a T-shirt -- no matter how offensive that slogan might be -- is therefore immoral.
