"anyone claiming the UK’s legal migration is any sort of problem right now, or in the past, should probably not be listened to in any way shape or form for anything they have to say on the matter."

This sort of position is, IMO, disgusting and immoral. I cannot express how appalled I am that someone would state something like this. Anyone who's a citizen of the UK most certainly has a right to express their opinion on legal immigration, either in favor or against.
