Years ago, during a nine-year stint in London as an economic migrant, I was sitting in a pub looking at Leeds United v Someone-or-other in a match of no consequence to anyone in the pub but me (it was an Irish pub called Mulligans, in Stratford, East London) when a black man walked in.
He was a little the worse for wear, but wasn't really bothering anyone as such - unlike the witless, ignorant gobshite you will see in the video above.
Anyway, one hero in the pub descended from his regular pew beside the bar, and ejected the reveler. He came back dusting his hands proudly before declaring in a strong Irish accent (as is mine, by the way) "just because he's black doesn't mean he has to be stupid", seemingly oblivious to similar bigoted attitudes towards he and his fellows in that pub and elsewhere in the UK.
I left in embarrassment.
Have a look at the video. It needs no further comment from me.
