It’s not a competition, but what you’re saying is simply not true. I understand Chabad’s stance; it’s pretty much the same as my own. But, if you don’t hold like the VaYoel Moshe, then you can’t claim to be more anti-Zionist than Satmar.
Chabad accepts the reality that the Zionist movement was founded and led by people who hate the Torah. Satmar, on the other hand, wouldn’t care if it was led by the Tzadik Hador. They hold it’s inherently assur and that the state is essentially assur b’hanaah.
This would be like a guy selling chometz during Pesach and saying “in theory, I’m even stricter about chometz than frum people; I just happen to derive benefit from it anyway since it’s here.”
