if you want Hitler to include Muslims in the holocaust (which basically seems to be what you want) your goner need a post 1900 POD or at most the latter half of the 19th century. IMO to have this happen you need immigration from a Muslim colony that somehow Germany manages to keep hold of post Versailles -god knows how they do- or for the Weimar Republicto have a major massive Labour shortage and to have Slav Muslim immigration ( though Hitler would have a bigger problem with them being Slav then Muslim). But in short of save huge massive enormous Muslim immigration Hitler is always going to have a bigger problem with Jews than any other minority group.
if your main intrest is the 1683 POD of your orignal post I would suggest doing a thread about it on its own. one thing though to evey one saying its unlikely that Hitler would be born don't most the TL's on here have OTL people born anyway ?
