To be fair, my Facebook feed this morning was brimming with Remain voters spouting that 52% of the UK population are racist bigots, so HaydnH's comment is based on fact.
I'm in no way suggesting, of course, that all Remain voters think that way!! There is however a vocal contingent that are cheerfully labelling Leave voters as racists and bigots.
Unfortunately I think you are right, both sides seem to have a very vocal minority who clearly don't speak for the majority. Social media in all it's glory
