This is my point, you blame the "white flight" and when shown evidence by Cyril that English people moving to Wales hasn't had the impact on voting here that you think it has, so now you've moved on to another aspect of England/the English that's the cause for it.
Either you're not self-aware about your hatred of the English (which is worrying) or you're pretending to us that you don't recognise it. I hope it's the latter
