It is not illegal to insult anyone in the Netherlands however it is illegal to incite violence against a person or a group.
Gert Wilders views maybe reprohensible but he stayed just the right side of the law - although I do believe the Dutch authorities are trying to make a case against him stick.

"Deaths in the Bible. God - 2,270,365
not including the victims of Noah's flood, Sodom and Gomorrah, or the
many plagues, famines, fiery serpents, etc because no specific numbers
were given. Satan - 10."
