The entirety of the US would get a lifetime ban if we did that.
Have you not heard what it's like for an Arab or Muslim going through Israeli airports? Sure, they'll be detained and deported at most, but that's enough to exclude the idea of visiting to give a conference talk.
You manage to get past, let's say, Saudi customs as a trans person, get ready for jail time for the crime of existing. Not comparable.
This is more of a special privilege granted to Israel specifically.
Bad example since Jews are generally the ones who were getting cleansed. They were evicted by extreme Christians, then murdered by Nazi Germans (remember when US and Canada did not accept a shipful of Jews fleeing gas chambers so they had to go back and die?) and 1948 is when Arab League attacked the new country the next day after it was created.
Meanwhile Muslim people in Israel lead far better lives than in many surrounding countries with access to good healthcare, education etc. There is certainly no cleansing and people choose different schools because they speak different languages. There were certain moves like demoting Arabic from its previous role as official language 5 years ago but then how many countries in Middle East even recognize Hebrew? I've visited it once, you should perhaps visit the country yourself some time and see if you find all that terrible cleansing and apartheid. Maybe compare to all the Muslim countries around while you're at it, too.
A better example would be Qatar with its exit visas, not only not sanctioned but football world cup was held there
And you know what? Africans had nothing to do with it
