the OP was saying our leave vote validated these people's actions and I am saying 17 million people are not racists therefore how can their vote be seen as validating this awful behaviour.
I don't think it was OP saying that the Leave vote validated this behaviour; it is the racists who are saying that. OP was simply spelling that fact out. The mindset of these fuckwits was, essentially: "I want forrins out. Leaving the EU will get forrins out. Therefore I must vote Leave. Oh good, we won, so all the forrins have to leave. 16 million people therefore agree with me that forrins are evil. I personally have won and I have a bigger willy than anyone else so I can do what I like. Oh good, there's a brown person over there that I can now freely bully because the referendum vote was on my side."
Sorry, Leave voters, but that's the company you chose to keep. Live with the consequences of the decisions you take and stop acting all injured about it or pretending those consequences don't exist.
