What does the word “Zionism” mean to you?

I feel like i’ve seen this word used online in lots of different ways, lots of times comparing zionists to nazis and i’m wondering what everyone’s thinks what its definition is. like for example, I personally believe Netanyahu is a war criminal and the current government is a disgrace to the jewish people, but at the same time I believe in some form, somewhere, there should be some kind of jewish state - and a palestinian one of course. Would that make me a zionist?
