You could absolutely say, with no surrounding context, "Palestinians deserve to live", and have half a dozen people call you antisemitic, as if you were
1: talking about jews or Israel in the first place,
2- saying NEGATIVE things about those groups, or
C, implying that two groups of people can't exist at the same time.
And a dozen other people nearby will nod their heads in silence as though the person calling you antisemitic was in some way correct in their assessment.
Make no mistake, there are plenty of people in positions of power, who could all make sure this doesn't happen.
They aren't. Mostly because they want it to happen (also to own the libs) , or because they don't seem to realize we are in fascism times and think "surely there is a good reason for this"
They are giving it to him.
