I think we would need stats before making that first conclusion. I've seen a lot of favorability polls of Israel amongst Jewish people, but not sure I've ever seen an explicit ask for Zionism or its definition. I'm sure it's out there, but I wouldn't expect the OP to take that for granted without a source.
Your second sentence is arguably correct, but lacking a lot of context and really not presented from a neutral standpoint like the other commentor and I were trying to strike. I think when people are looking for raw information, it's fair to provide that with as little bias as possible, especially on a heated current issue. And fwiw, I likely agree with you on that issue.
