@serge i don't actually know what zionism is. My first introduction to the word is the protocols bullshit and I've kind of been wary of the term forever. Is zionism a real thing and, if so, what are its basic tenets. I've also been wary to ask about it because I don't know the motives of people on the internet very well. But why not now? No need to answer, I'm sure you're busy, I won't be offended.
A somewhat medium answer:
There's Zionism and there's a second aspect, which is simply "Jewish safety".
Israel holds 7 million Jews, or roughly half the world's Jews. Of those Jews, roughly 60% are, or are the descendants of the expulsion of the Jews from the MENA, an event where virtually all Jews were kicked out of every middle eastern country:

Of the others, many are Holocaust descendants, and many are from the former Soviet Union, where they also suffered antisemitism, as well as other Jewish refugees from around the world.
In other words, a nation largely composed of Jewish refugees, and it's illegal for Jews to own land, or in some cases, even be on Palestinian land, as well as Israel's neighbors, who have tried to destroy it more than once.
Anti-Zionism is the call for Israel's destruction, and thus the call for the death or forced expulsion half the world's Jews, most of which know no other nation.

Because of that, many Jews (myself included) feel that calling for the death of half the world's Jews is an antisemitic act.
So there I've defined anti-Zionism, and not Zionism itself, so now I will define Zionism- largely through citing others.
Zionism is, at its core, the belief that Jews are unsafe in the diasporatic world and that due to the constant realized threat of antisemitism (as expressed by regular attacks on Jews), the best path to safety is to have a nation state that we can go to.
Everything else after that is up for interpretation, including the political structure of that nation, whether it should be on our ancestral homeland or not, the motivations on why it should exist (secular or religious) and where the borders of the nations lie.
In fact you are likely to find that as the old saying "Two Jews, three opinions" goes, it's even more for Zionism.
Now for resources to cite- I'll give you only a few.

A resource I think is "OK" but a bit dry is this blog post:
https://www.rootsmetals.com/blogs/news/zionism-what-the-heck-is-it
Another resource that's fairly accessible is this video on Zionism from Unpacked:
https://www.youtube.com/watch?v=N2zYYQCYUvY
While I don't tend to like resources that cite the bible, even if you don't believe that G-d told Abraham to make a people, then you can simply understand it as *this is what Judaism teaches* and that this land discussed existed as Judea and the land of Israel thousands of years ago.
There's another video from Unpacked I like less:

Beyond that, I think that the Wikipedia article is a good resource, though it only references modern Zionism and not the other two Zionist movements that came before it.
https://en.wikipedia.org/wiki/Zionism
In fact, I think that you may even find the Zionism Wikipedia article a better starting point.
What you will find in all of these resources is that the core idea of Zionism is set, but none of the details.
