Every leftist I met who refers to Israel as a settler colony wants all Jews to be removed from the Levant (in some cases killed, since lefties tend to view Jews as 95% upper class anyway), and you never seemed like an exception. Moreover, theoretically all immigrants de facto qualify as settler colonists, since a home for a rich immigrant could have gone to a working class native-born family.

I certainly do not want all Jews removed from the Levant. I don't particularly want any Jews removed from the Levant (or anyone removed from anywhere, for that matter!). In fact, my whole point was that one of the primary reasons settler colonialism is bad is because it involves the coercive removal of people from their homes/communities. It would be fairly hypocritical of me to then advocate for the removal of all Jews in the Levant, would it not?
It's also worth mentioning, of course, that there were many Jews living in Palestine before the state of Israel existed. There's no reason that the existence of a Jewish apartheid state in the Levant is necessary for the existence of Jewish people in the Levant. But in any case, "who came from where first" is ultimately not something I think is particularly relevant. The problem with (settler) colonialism is its coercive nature and its destructive consequences, not the idea that "the land was taken from its rightful owners". Land does not have rightful owners, it's a bunk concept.

Well, there are a couple of things to address here. One is that settler colonialism typically refers to coordinated coercive action by institutions, not just randos moving around and potentially causing harm as a side effect. When similar effects (people being forced out of their homes) are brought about by disorganized individual action, it's typically talked about in the language of "gentrification". Of course, this is nothing but a semantic point. But since your whole issue seems to be semantic (my referring to Israel as a settler colony) I'm not sure what to tell you.
It's also worth mentioning that the prototypical example of settler colonialism āand indeed, the example found in Israelā involves a very direct type of population removal. Like, some government dudes show up at your door and say "hey, we're taking your house, get out" and that's that. If you want this not to happen, the only option is for the government to just stop doing that. There's no way around it.
By contrast, the way gentrification forces people out of their homes is through a relative Rube Goldberg machine of markets and systems: rich out-of-towners start to move in, they attract more demand for living space in the area so rent goes up, you still make the same amount of money so now you can't pay your rent, your landlord then has the legal power to evict you, and finally if you don't go along with it the police are called and you're forced out. This does still end with government goons showing up at your door and saying "leave", but there are a bunch of steps in the process before that where the Rube Goldberg machine can be interrupted. This is what housing policy is for. There are all kinds of policy approaches solve the issues with gentrification ārent control, government- or community-guarenteed housing, whateverā which one may like or dislike to varying degrees but which don't just involve saying "you are banned from moving neighborhoods". There is no policy solution to the problems of Israeli settlements without just saying "Israel has to stop doing the settlements".
And as a bit of a reality-check to all this abstract discussion, we should definitely keep in mind that most immigrants are indeed not rich immigrants, they are poor immigrants (a special case of the more general fact that most people are poor people). A typical (poor) immigrant moving into your neighborhood is unlikely to make property values go up.
Anyway, all that being as it may, what I'm actually advocating for with respect to Israel is basically this: (1) an end to US military aid to Israel, (2) an end to the Israeli settlements and the forced removal of Palestinians from their homes, (3) an end to Israeli military occupation of Palestinian territory, and (4) an end to the apartheid structure of the Israeli government more generally. None of this has fuck all to do with removing Jews from the Levant.
