I understand that it's trolling, even Richard Spencer is trolling more than he's really leading anything. And I would have had no problem with the Nazi dog but the line about "gassing the jews" was just horrible, he lost my sympathy by thinking that line was in any way funny.
Some people say humour should have no limits, I don't quite agree (and I'm deffo not a PC-type).
I don't think it's right he was arrested to be fair. However I also think he's a massive idiot and he seems to be trading on that now.
What I think's sad is that in his head and a lot of other people's, the space between not being arrested for something, and something not being morally dubious doesn't exist. The Charges were dropped and he obviously thinks people were impressed with his behaviour. It's pretty sad and I hope one day he grows up a bit and loses a bit of weight.
Whenever he's challenged on his behaviour he seems to go down the "no free speech line". It's odd really that he can't think of his behaviour being wrong unless in a criminal capacity. Ah well, I'm sure him and his mate Gandalf of Moordor will convince themselves that along with Christine Hamilton they are taking over the world.
