It's quite simple.

Auschwitz was a horrible place for Jews. The Nazis were responsible for bringing the Jews to Auschwitz. Any decent person did what they could to keep Jews from winding up in Auschwitz and tried to get the Jews in Auschwitz out.

Canada is a racist horrible place for minorites. _____ are bringing minority immigrants to Canada. Any decent person should do what they can to keep minorites out of Canada and try to get minorites out of Canada.

If you accept that Canada is this awful racist hellscape, then doing anything other than preventing minorites from coming here and getting the ones here currently out means you're the same as the Nazis.

Unless, you know, Canada isn't a racist hellscape?

Also, and my history may be fuzzy, but I don't recall the Jews fighting to be able to go to Auschwitz. Almost seems like all the minorites fighting to come to Canada would intrinsically mean it can't be awful for them here.
