A quote from the guy himself:
"
For me it is very hypocritical to treat Muslims, Nazis and Marxists differ. They are all supporters of hate-ideologies. Not all Muslims, Nazis and Marxists are conservative, most are moderate. But does it matter? A moderate Nazi might, after having experienced fraud, choose to be conservative. A moderate Muslim can, after being refused to enter a club, be conservative, etc.
It is obvious that the moderate supporters of hate-ideologies, at a later date may choose conservatism.
Islam (ism) has historically led to 300 million deaths
Communism has historically led to 100 million deaths
Nazism has historically led to 6-20 million deaths
ALL hate ideologies should be treated equally."

Because the Daily Mail calls him a Nazi doesn't make him so.
