No idea why the link doesn't work for you but are you honestly seeing you missed all of these from three years previously?.

And the most recent issue as in the link is worse.n
I managed to open your link N S, 2-5-12 and 14 were outright racists as described, number 10 Harry Perry, I thought was very odd with a bit of everything thrown in, I wouldn't want to see him in any position of authority.
The rest were mainly anti-Islam, which might not be very likeable but anti-Islam is anti-Islam it isn't racist, the others were just the sort of thing you might hear in any pub in anytown, but none the less would I M O disqualify them from office rather than see them as deep rooted racists even though I can see how these sorts of view are found so very objectionable by lots of people and they were after all rejected by YUKIP.
Of course I can also see how these kinds of people would be even more objectionable to those on the loosing side of the referendum and I'm equally sure the looser's would be on the look out for any faults in the people they oppose, when that's all they've got left.
I'm not exactly a follower of the supposed good book but it's not utter and complete rubbish, I'm sure there's something in it I read about who should be throwing the first stone.
