Judging by his name, i'd say he is from Wales, not England. When you are accusing people of something as serious as racism, you should probably get your facts right.
Wales and England have a dislike for each other, especially when it comes to sporting events. That is the logical reason for why Welsh hates Khan. Incinuating that he's racist, without decent proof, and then not even getting where he is from right... it just makes you look dumb.
I bet he hates the white guy Froch waaaaaay more than he hates pakistani khan.
It's rare that I like an English boxer I'll admit to that, but my dislike would never stop me from admitting when they are good or not, Khan is a good boxer but I still feel he has flaws which a great f!ghter like Mayweather would expose without breaking sweat.
Khan/Bradley would be an interesting f!ght, Bradley has much better feet movement then Khan and is a f!ghter who likes to move forward (Khan doesn't like to be pushed back) however Khan's speed could be detrimental to Bradley as he could jab all night.
But saying that^ Bradley's defence is excellent, so he could possibly dodge/defend Khan's jabs and work on Khan's body.
The f!ght would be very close and if Khan does beat Bradley the next step up from that is to face a f!ghter like Mayweather, he's not ready for that imo.
