Is anybody else alarmed at how many people don't see the parallels? (Tagged as politics because idk how to tag this)

I've been rather alarmed and disgusted about how some people can't see the parallels to what's been happening under the Trump administration and what happened when Hitler was in power. I'm not sure about the rest of the world, but the Holocaust has been ingrained in my memory from the time I was in 6th grade to now. What I'm not understanding is was the Holocaust not taught in some places or were people not paying attention? Because I think this many people not drawing the parallels to Nazi Germany and now is terrifying. Sometimes it feels like I'm the only one that had drawn the parallels. I may not remember every miniscule detail about the Holocaust, but I know enough to where I can see history repeating itself.
