Same thing happened during 9/11. Muslims saw suppression, bullying by the police and no one covered it. Then the tables turned on maga republicans after j6.
My understanding of Hamas is that they are not considered a legitimate army, but if they were they would be guilty of an insurmountable number of war crimes (not unlike the IDF as many would say). Showing support for such things is beyond reasonable accepted discourse in my home country.
Any excuse is good when you have power and want to justify repression. For example they tried to claim that the slogan "from the river to the sea Palestine will be free" is genocidal. Quite a jump. (Meanwhile, the Likud's platform says "from the river to the sea there will be only Israel" but that's fine).

They killed much less civilians than the IDF did, and they are not invaders nor illegal occupiers of someone else's country. What is acceptable or unacceptable is decided by those who are in power, and they are currently protecting a country whose prime minister in charge is wanted for crimes against humanity.
