Sorry, but I am having a hard time connecting the concept of "people are unhappy with government policies related to immigration" and the concept of "people are picking up crowbars and beating in the skulls of random immigrants on the street".

Would you care to elaborate the connection you claim exists there? Your post seems to be giving a tacit nod to the violence of bullies.

Sorry, but plenty of Westerners have been unhappy with government policies related to rates of tax collection, but somehow we do not see mobs of bullies beating in the skulls of tax revenue workers on our streets.

And so I think there is a difference between mere opposition to a government policy and what has happened on a street in Britain, the latter being far, far darker than you seem to pretend. 

You nonchalantly invoke a thug state with mob rule, and a good clue you are off base is when Andrew from Toronto, Guantanamo and Doctor Demento are all lined up together on the same team against your statement...
