You are defending assaulting strangers who have done nothing.

The internet is wild.

Yes. Downplay it all you want but it's still assault. Especially when acid attacks are not unheard of.

This justifies assaulting people how, exactly?

Screw these guys. Whatever your position on the matter it's not the tourists themselves who are culpable, but the national and local government for allowing their economy to be so reliant on tourism.

It doesn't justify assaulting and harassing people in the streets.

Barcelona is not the only city in the world that attracts a large number of tourists. Many cities attract more. Yet Barcelona is the only place I see with so many of these xenophobic nutjobs.
