That's a good question, certainly not something we're taught in schools/media about nazism. I'm posting this here because although it's usually a sign for nazi propaganda ahead, i find it's a good reminder that when a politician proposes to "deport" people (such as Zemmour in France proposing to deport muslims), genocide is how this ends up in most cases.
No, deportation is not more humane. Fuck all nazis, even those wearing a tie/suit and speaking on public television in the 2020s. Did lemmy know social-democracy and authoritarian communism is what gave birth to fascism as we know it? Next week in "did lemmy know", we'll talk about anti-muslim genocides in the USSR.
Uhm, you picked a bad timing with /c/asklemmy being brigaded with anti-semitic shitposts.
But in general yes, the historic collaboration between pre-war zionists and Nazis is interesting. Initially the Zionists actually thought the Nazi persecution of Jews would help their cause... but of course that feeling quickly went sour...
