I hate videos like this. Designed to create animosity towards specific groups. Could only manage a couple of minutes of this garbage. If this is all the OP is capable of posting is it worth being on this site?
I found it quite interesting as I have never watched stuff like this. I did not watch it all, I fast forwarded and dropped in so I may be wrong in my comments.
I agree with the sentiment you are expressing, the guy is a dickhead who is winding up others just for the fun of it. I thought it was interesting how his behaviour was so like people are on social media - one person called him a fascist so his belief system is that everyone there has called him a fascist and he gets worked up more and more by it and is challenging everyone. People get fed up with him because he is a dickhead and thrusting a camera in their faces and he takes that as support for his outrage rather than reflecting on his behaviour.
I kept thinking who would want to be a police officer dealing with people like him.
