The phrase was created with the explicit intent to destroy Israel. We can equivocate about the intent to destroy Israel as being genocidal, but as I explain, Palestinian activists consider it genocidal intent when Israeli politicians talk of destroying Palestine, so I use their own standard. It may be that people who use this phrase do not intend destruction of Israel, but they are using a phrase which was created explicitly to call for the destruction of Israel. I don't accept that there is any good faith way to claim the term has been "reclaimed." If I say "heil Hitler," and follow it up with "but no genocide or any of the bad stuff Hitler did," it doesn't erase the first part of my sentence. In fact, the second part is antithetical to the first.
