Obviously, Mohammed was a major anti-Christ false prophet and his false religion has been a mighty scourge against Christ and his Church. That said, I would argue that today and for at least the last century it has been far, far less influential directly and indirectly in corrupting the lives of Christians and sending them to hell (mostly through sins against the 6th and 9th Commandments) than has Judaism. I would also argue that the results of Judaism via such entities as Israel, AIPAC, Planned Parenthood, the sex industry, and the world's centralized banks and usury to name but some of the major things has had a far more devastating impact in terms of a culture of spiritual and physical death in the modern world than Islam.
As for Wilders, if he was of the same stature and was blaspheming Judaism and the "Holocaust" (putting aside the semantics/question of whether it actually be possible to blaspheme that which is so lacking in holiness) to the same degree he has been going against Islam and Mohammed, I think it would be fairly safe to say that he would not simply be continuing to receive death threats, but that the Mossad would have terminated him with prejudice years ago.
One final word about The New American --it is nothing, but a Judeo-Masonic rag which shills for Israel including its staunch defense of that bastard terrorist apartheid state against any and all charges of its major involvement in 9-11.
