Firstly:
Okay now for the post.
When Palestine is liberated, I think the vast majority of settlers will either be [redacted] or forced out of the region. There is no way that any Arab in the region will accept having a settler in their land, and the settlers know this. The plan will have to be a mass exodus for the west, both for their safety and livelihood (I can see many going into ghoul industries like defense, tech, and police training).
That being said, how would you react if your country decides to accept settlers? Would you support the move? If they were going to live in your community/ neighborhoods how would you feel?
It's not about optics, you're doing every refugee and migrant a disservice by lopping ex-settlers with them. Refugees and migrants don't steal land and attempt to turn the native population into second class citizens, that's just a reactionary myth.
Except the Israelis actually did do that, so you can't say they're the same thing as Syrians, Sudanese, Congolese, etc escaping war and genocide.
You don't have to "punish" people on behalf of the Palestinians, but you also can't act like they're the same thing as South/ Central American migrants coming to the US to escape poverty and violence just for a chance to give their family a better life.
