The entire reason the word is problematic is because it is so overloaded. Even setting aside the white supremacist baggage for a moment, purely descriptive definitions depend on time, place and context to determine whether you mean that the Jewish people should have representation in Palestine, the creation of their own independent state, the continuation of their own state, or a justification for colonialist expansion in the Levant. The term is historically favored by white supremacists specifically because it is a dog whistle which has plausible deniability to mean anything from a historical retrospective to actual antisemitism.

For decades, thoughtful critics of Israel have intentionally avoided invoking the term to separate their analysis from hate groups. And this is not a difficult thing to do. It is quite easy to articulate specific problems with Israel's statecraft. There are many things to choose from, so when people choose the dog whistle instead, there's a good reason to see it as suspect. Israel also understands this. They prefer you choose the bumper sticker instead of sober analysis, because it is easier to discredit.
