He is going to have to fire you anyway otherwise his Kike overlords will fire him then appoint someone to fire you
Also Scholo Sands and Norman Finkelstein have moderate takes and are actually claimed to be of Ashkenazi Jewish ancestry
Shlomo Sands claims Ashkenazi Jews are not descendants of Israel but descendants of converts although I mjght be misrepresenting him through over simplification
Also Arthur Koestling ( spelling ? ) has made similar claims in a free online audio book
I spelled his last name wrong
It is the thirteenth tribe by
Arthur Koestler
It is a free audio book online and even on youtube
You do not have to go full direct and start out calling the kikes evil
You can point out that they are not actually primarily of Israelite ancestry quoting from moderate people who call themselves Ashkenazi Jews
Also it might be nice to say there is this awesome Jew I read and listen to called Steven Hassan
If he learns about how cult "mind control" works through information phobia from Steven Hassan material then he will be more open to listen to ideas he was afraid of like criticism of Israel
By quoting sources claimed to be Jewish at the start you make him feel like you are on his pro Jewush side so he is more willing to listen to
I would try to start with Hassan first
