You are Anti-Semitic

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.
