Disclaimer: I don't think people are going to be round up and killed, but there's a serious lack of historical understanding when dealing with this sort of comparison.
It's not like Hitler walked into office immediately saying "Turn on those gas chambers, we've got cookin' to do!" Also watch "Don't be a Sucker 1947" on Youtube for other "rise to power" stuff.

Hitler scapegoated Germany's problems (being poor AF after WW1) onto smaller groups of people. The larger groups of people took the bait and it fostered a "common enemy" with Hitler. So now anything Hitler wanted to do to them was acceptable because since they were enemies of Hitler they must be enemies of the German people. Then came heavy segregation, and then came the Holocaust. Since Hitler controlled the media AND the school systems directly, nobody really knew what was going on so nobody could stop it. Lots of German soldiers only found out about the Holocaust after the war had ended.

I thought this would be a controversial image, given it is on the Antifa gallery and marked as NSFW, but… yes, this is pretty much on point and a rather obvious conclusion.

Just to add a bit of humor to this, here is a semi-related image:
