So the difficulty is:
”you can’t tar all Muslims with the same brush”
”Muslims believe x, y or z”.
You are left with two statements that are fundamentally contradictory. Either you will sit there and analyse, one by one, the beliefs of all 1bn + Muslims in the world at any given time (given that of course as anyone can believe anything, beliefs can also change over time), or you can accept that there are some things that Muslims DO believe.
Now given that Islam doesn’t have a single central doctrinal authority (like Protestantism there are many variants) you can’t really say “all Muslims believe x, y or z”. Because as far as it goes, as many Muslims as there are, there are Muslim beliefs. However there is one thing we can point to which indicates a fairly anti-Semitic ground from which this springs:
Hamas
Islamic Jihad
ISIS
The Iranian Caliphate
Al’queda
Hezbollah
are all explicitly Islamic organisations and they are all explicitly anti-Jewish (and this is a fairly small sample). I will note that Hamas in its recent revised constitution changes the name of its target from Jews to “Zionists”, but frankly how did it know that the 1,400 it murdered on the 7th October were all ‘Zionist’ Jews (I.e.: Jews allowed to be murdered) as opposed to just Jews that shouldn’t be murdered?
Islam has a problem with anti-semitism. Even if analysis of the Koran doesn’t specifically justify it, a vast quantity of Islamic scholarship has since justified Islamic anti-semitism. Even if we can’t say that Islam is anti semitic as such, we can ask the question, very fairly, of why does Islam provide such a breeding ground for such openly and directly anti-Semitic organisations?
