Country’s law prohibit the denial of holocaust…If muslims have a problem with it they can take it to the court(which they have in case of wilders)..But since muslims themselves(atleast in pakistan) are so good at cooking theories on people who kill their own civilians no wonder no one is moved on theories on holocaust..
Muslim countries prohibit n things and claim to be exp(n,n) things…Anyone wanting to go against the prohibited is asked to find a place in the free world or silenced. So is the situation in netherlands..few hundred dollars of plane ticket is all that is needed..
