Obviously calling other people names doesn't bother you either. The term Israel-first is pejorative. In fact, even the term America First presumes that those who disagree with you are not Americans first.
Given your cancellations, I have a new name for you, an anti-Zionist Firster.
The term Israel First is an accurate description of those who place the welfare of Israel above all other political concerns. The last few weeks have shown just how many such there are in positions of influence in this country. Many are Jews, many are fundamentalist Christians, some like Gingrich are just bought and paid for.
