Nope. He does the salute twice before saying the ‘my heart goes out to you’ plausible deniability attempt. Which makes it much less likely to be just a simple gesture, and also makes it very very clear that the crown is cheering the salute, not the line which comes later.
No one (except for a very few nut jobs) is blaming Jews for the genocide that is happening, they’re blaming the state of Israel. The current government and individual people making the decisions. Disagreeing with apartheid Israel does not equal ‘blaming jews’.
Also, look into Christian Zionism. There are a lot of literal nazis and other antisemites who are thrilled about backing Israel right now, because they think that this is all part of a prophecy that brings about the end times or something… And this prophecy does not end well for Jews. So no, supporting Israel does not necessarily mean someone isn’t antisemetic right now either.
