Minor update: This has more than 8m views on Twitter and I've seen a lot of right-wing political commenters I'd never expect to be Sam Hyde fans sharing this. It's definitely escaped containment.
I'm glad it has reached a lot of people, it's a pretty good video - well-shot, well-voiced, deftly mixes all sorts of humour with some very clever commentary on the issue. Sam Hyde did an excellent job on this one.
