For some reason I didn’t make the connection before, but if we pretend that she’s trying to be progressive, her argument is tailism. She’s not trying to get people on her side, she’s deciding her side based on where she thinks more people already are without any interest in agitating for people to develop better positions, to benefit a good cause rather than just a popular one (and anti-zionism is characterized as unpopular at first before calling it popular to accuse it of giving Nazis cover). It’s a perfect microcosm of her politics, where she thinks “having power” means conforming to the group that has power so they support you, as though you can thereby accomplish anything but what that group was already doing.
