Let's just go with your belief that the majority of people in the UK are idiots* and > 15% of them are racists, how do you intend to produce these "less racist feelings"? Cos call be crazy but I don't think shouting "racist idiot" at them is really going to work.
*of course nothing like the majority of people in the UK voted Conservative, so who are actually calling idiots here? Non-voters? Anybody who didn't vote Labour?
I can judge them without wanting to help them.
