1. Israel is not Judaism, even though its fascist state claims ownership over it (did you think the Star of David is the same thing as the Israeli flag?)

2. A star of David does not have the same meaning to it as the watermelon pin. One is a religious symbol, the other is a symbol of solidarity with a nation and people who have been fighting against genocide for a century that is abstracted from the Palestinian flag exactly because of how complacent our settler-colonial system is with that genocide.

3. I reckon you haven't had to deal with medical professionals as a member of a vulnerable group, because there is a very wide range of political opinions that these people will openly express with impunity when it is consistent with hegemonic values. To start actually firing these fucks when one is criticizing genocide is hardly a principled choice.

On top of all that, I'm fine with my doctors wearing fucking religious symbols because, guess what, they can simply not wear one and have their views effect their ability as physicians anyway. Restricting religious identity would be disproportionately enforced on vulnerable groups like Muslims again.
