Moz supports For Britain primarily because they want controlled immigration - their animal rights stance is a bonus. He clearly said they are the only party that can "save Britain".
The engineered mass immigration in recent decades of, in particular, Africans and Pakistanis has turned Blighty into a more dangerous place. It was announced last week that blacks are responsible for 50% of Britain's knife crime. That's outrageous. A group comprising 3% is responsible for half of all Britain's knife crime.
There needs to be an open discussion on this. Instead we get full page advertisements in newspapers such as London's Evening Standard (last Friday) telling us not to be racist, when there should be full page ads telling blacks to stop stabbing people en masse for fun. That kind of behaviour isn't xactly endearing and won't make other races like you, no matter how much they are emotionally blackmailed or forced by law.
