People justified their anti-Muslim hate after 9/11 with similar statements about polls saying most Muslims saw Bin Laden in a good light, and have anti-West views.
Not saying I agree with any of it, but I find the parallels illuminating. If anyone wonders why there's more anti-semitism now, s/he can perhaps compare it with how all Muslims are condemned as being members of a barbaric sect after any terrorist attack (yes, even attacks where the perpretator doesn't claim to be doing it for Allah).
Hold on, you're doing a little gymnastics here. People are very deliberately talking about Israel being in favour of the genocide, and quite understandably saying that their government should not be supporting Israel - with "not supporting" meaning anything from BDS to simply not handing billions of dollars to them. Some of the most vocal and strident supporters of this are Jewish. The groups attempting to connect the genocide to Judaism are the US, British and Israeli governments & news media - who are all broadly pro-Israel.
Additionally the anti-Muslim hate was not "ah let's very justifiably cut ties with some mad country" it involved widespread and open islamophobia, calls for mass deaths and indeed invasions of muslim-majority countries.
I wouldn't be surprised if the results of a poll for actual genocide would be the same, but expulsion is not genocide. I really wish people would stop diluting the meaning of genocide at every opportunity.
