No he commented on someone else talking about “white tears” as “his favourite drink”. Yes it’s not good. But the question was whether it was better/worse than what Farage has come out with down the years and I don’t think it’s vaguely comparable.
With social media it will follow him for the rest of his career in politics or not, rightly or wrongly. Same for the Rochdale Labour bod. I think there has to be a tiny bit of leeway given to something said by a young person on Facebook just as some people at that age have some pretty bad right wing views but grow out of it.
