What's the point in asking for comment?
I can give you the answer "just because 1 or several candidates say racist things does not make the party racist, lib,lab,con members have also said things does that make their parties racist??"
The very fact of overwhelming terribly coincidental weight of examples of UKIP members being raging racist homophobes is totally not the point as they don't write it down in their policy documents.
UKIP supporters will completely ignore the fact that behaviour and attitude and actions state more about a party than any official policy and anti UKIP can't actually prove that wrong because how can you?
The very fact that what every major party writes and what they actually do is very different totally passes them by. We have years and years of evidence for what lab/lib/con attitudes as a holistic view actually are as they have all been in power and until UKIP voters are willing to open their eyes to behaviour then I guess we can't do anything other than pray to god they never get into power to prove that all these displayed behaviours are in fact far more realistic that the policy document which may as well be used for toilet paper for all the truth they hold.
By which point I'll be packing my "oh fuck" bag ready for the Gestapo to come knocking.
