My reaction is to think that this is going to be a problem. Coming to the same conclusion for completely different reasons helps specifically with the conclusion but then outside of that conclusion, you're still going to have a problem. It doesn't help very much.
Leftists who dislike Israelis genociding Palestinians so they dislike Israel aren't going to side with you trying to exterminate jews in your home country to improve your quality of life. They'll just accuse you of genociding jews then take the side of jews. If Mexicans in Mexico become a huge problem such that the USA invaded Mexico to solve the Mexican problem, these leftists would side with Mexico against the USA in the same way they side with Palestine against Israel.
These leftists are not your friend just because they got to the right conclusion on Israel. That happens from time to time and perhaps it can be capitalized on like promoting ending all American foreign aid to Israel. Both sides can agree on this. But overall, their way of getting to the same conclusion is ultimately the problem and they'll still be your enemy once the dust settles on the one thing you got to the same conclusion on.
