Does that make him a racist?
You are a racist and then a voter, not t'uther way around.
So I will repeat the question. Is my Bangladeshi friend a racist because he will vote UKIP? Are you saying that only 'white' UKIP voters can be racist?
(He won't answer)
He already has answered!
Don't do a norcon and perpetually demonstrate your inability to grasp the facts.
Being a racist probably would influence your choice at election time, but being a UKIP supporter or any other party supporter does not mean the you are a racist. Suppose you just want out of EU, that's not a racist attitude. It's a choice.
Let me elucidate a little further, perhaps by using the smoker/non-smoker analogy:
Some people decide to change their views/attitudes. For some it's an epiphanic moment and they just change.
Others need time to adjust, but are determined and persist, although occasionally failing but trying again.
Others never do realise their errors and continue as normal.
Some do realise their poor behaviour/attitude but persist in some militant attitude decrying all who oppose them.
Other never were in the fist place.
Whereas with voting, you can vote one way this election but another way at the next election, your choice.
Some may suggest that you're gullible for believing the gospel of some politicians, but any way is your choice and you're entitled to it.
