John Selwyn Gummer (though he tends to drop the Selwyn these days - too elitist) is well known for his hatred of Jehovahs's witness , Mormons and other groups. He was one of a few MPs who dumped the Anglicans when they voted in favour of women priests and converted to Catholicism. Puzzlingly for someone who publicly slags off groups that he determines as cults , he describes Graham Leonard (former Bishop of London) as his guru and tried to use his political influence to get him appointed as an archbishop in the Catholic church.
His most famous moment was during the BSE scare in the 90's , getting his four year old daughter to eat a hamburger. He is generally regarded as "a bit of a plonker" , as we say in these parts!
Ironically , if he was to say that he "hated" Moslems or Jews, he would be prosecuted for religious bigotry (if he was foolish enough to say it outside the House of Commons). In the UK , the only religions you can openly criticise are Christian.
