A supervisor should understand the concept of respecting people’s boundaries. You could always say something like “Hey I’m not really in the mood to talk right now” or “This isn’t something I want to talk about”. Just a fair warning if you do this, you might get labeled as the odd one the same way you mentioned if you go to HR (the HR one would be a bit worse if I’m being honest).
This is Israel’s version of de-escalating an escalating conflict. Disgusting animals.
