This is all my personal view on this as of late and does not represent mod consensus.
I think there comes a point where a symbol loses any sacrosanct nature and that is long past when it is razed into the ground and branded on the skin of the indigenous by an ethnonationalist enclave that claims it as their primary means of representation.
The thing about symbols is they're ultimately contextual, we differentiate the Buddhist swastika and the Nazi swastika, I think we have the capacity to meaningfully differentiate the Zionist Star of David and the Jewish Star of David (color [blue vs. I've seen a lot of gold/yellow] for one). I think it's ultimately pedantic to dig in heels on it and I don't want to be exceptionalist with how I treat religious symbols on flags.
My current personal stance on religious symbolism in national flags is that national flags ultimately represent nations and not religions, and we have to contend with nations as they exist, even if they latch onto theology to make their representation seem sacrosanct.
My personal stance is that I think the best way to handle this if the change is made is to hotswap for the flag proper.
I'm sorry for being a blockage on this prior. Regret digging in my heels
