I sincerely hope this is a poor attempt at a joke because that kind of statement has contributed directly to the current situation. It is not antisemitic to criticize the Israeli government, Zionism, or the IDF and its actions. It is antisemitic to say the reason you are criticizing those things is because they are all Jews.
Conflating those two not only makes it impossible to speak out against the atrocities being committed, it makes violence worse against Jews.
I'm gonna have to go with Adam Savage. I loved Mythbusters and continue to watch his Tested one day build videos today and view him as something of a role model from a creative standpoint.
Also to chime in about your mentioning of Kevin Spacey, the guy is definitely a weirdo and has done some really tone deaf things (coming out as gay in the midst of being involved in sexual abuse accusations, posting videos of himself as Frank Underwood denying charges levied against him on YouTube, etc.), but wasn't he acquitted of or found not guilty in literally every sexual abuse charge that was brought against him? And in both the US and the UK?
