What do you think of banning a politician who is simply expressing his freedom of speech from entering UK?

Wilders has never killed anyone , never oppressed anyone , he is simply using his right for free speech , while ban him from entering the UK while bloody thugs , war criminals and m murderers like the israeli leaders, the saudi leaders or the chinese leaders are given the red carpet and received with all the honours , isn't this the proof that our leaders only care about business and electoral gains (the Muslim electorate in that case) and not about human rights and human lives .
