It's an excuse for advocating for ridding Europe of Jews while pretending to care about Jews, it allow true antisemites to pretend it's the ones who are against them who are antisemitic for not thinking that Jews should leave Europe and "go back to their country".
Just to stress this point a little more, guess who was very on board with Zionism:
