They’d have good company in mitzrayim- the Rambam in his time, R Ovadiah Yosef (was sent to be Rav there to be mechazek the community when he was young), and many others.
Just wondering, you’re ok with kiruv yeshivos in Russia and Poland and Ukraine and France? The people of those countries persecuted and killed us too, even before and/or after Hitler.
It is interesting that the chachamim made a cherem on living in Spain (some say it only applied to yotzei sefard), yet no similar official cherem was put on ashkenazic lands. So while it is unpleasant, it is also sometimes necessary.
