You are conflating the “least” among us with the “worst” among us. We actually only have sympathy for the former.
Have you ever seen what happens when we dehumanize our enemies? Have you seen what happens when we lose empathy?
These people you hate are, without a doubt, able to exhibit some pretty poor behavior. Most of them are children looking to belong, mentally ill, and those who prey on them - also probably mentally ill. Those that are adults were usually reached as children and come from abusive childhoods.
And you have no sympathy. It's okay, you're not required to. It isn't easy to empathize with Nazis. I can understand the unwillingness to try.
Would you empathise with Reinhardt Heydrich? How?
I think that Eva should have made some sacrifices to make Hitler happier, and it's not like she didn't know the reasons behind it because he was very vocal about his reasons as he would give vivid and gruesome descriptions of animal suffering and slaughter at the dinner table to try to dissuade his colleagues from eating meat.
I have gone through similar experiences so I can empathize with Hitler. This doesn't mean I agree with him overall, but that I understand and share his feelings on a specific subject.
If you strip the humanity from individuals, then you are refusing to try to understand them, which means you don't actually learn anything from the atrocities. When there's a shooting, you try to learn the motives and see where the system failed them. If they were exhibiting symptoms of an untreated mental illness, that lets us know that we need to work on providing better care and diagnosis. If we don't learn from history, then we are doomed to repeat it.
Once people start actively calling for the deaths of others based on race or religion or creed, that's where the fundamentally opposing ideologies are found that are only resolved through violence.
The lesson we should be learning from history is that appeasing racist fascists doesn't improve things, it only emboldens them by validating their beliefs as acceptable.
I'm not advocating stripping humanity from anyone, because I am fully aware that it is humans who create and commit these abhorrent acts. White nationalists, neo-nazis, whatever you want to call them are absolutely human. They are also all total shithouses that pose a threat to stability and harmony in the same way ISIS do.
They either stop what they are doing, or the blood of both sides runs in the streets. They are the only two options when it comes to beliefs like this. The problem is, the blood running in the streets is often what they want, and what we get.
I have had to lay down suppressive fire. I was willing to do so, but I hoped anyone I hit was killed quickly. I hoped they were killed quickly because, well, I didn't want them to suffer. I hoped they were killed because they were trying to kill the other scared young Marines beside me. Killing them was the only logical thing to do.
I'm not some hopeless naive child. I've personally witnessed human depravities that scar people for life, a fate worse than death.
You're scared of the people on Voat? Go there and read for a week. Go there and talk to them. Go there and belittle them, if you want. Have fun with it. Amuse yourself at their expense. Toy with them and make them dance for your amusement.
When you're done with that, maybe try to change some hearts and minds. You'll have gotten that out of your system and realized how powerless and ineffective they really are. They are powerless keyboard warriors spouting memes and racist slogans in an echo chamber full of logical errors and bad science and bastardized religious quotes.
Also, they hate fat people. Reddit kicked out FPH. No, really, those folks seriously hate fat people, but they tend to stick in their sub.
One sub really likes trees. Like, real trees, not pot.
They are humans. Deplorable humans, I agree. They even have a Linux section. As a Linux user, that makes me pretty deplorable too!
Seriously, go visit them. They are horrible people. However, they are mostly scared children. There's no need to be afraid. They are pretty universally powerless and reviled, even at the national political level - really. No need for hyperbole.
If you want, I will even introduce you on voat.co and you can go harass them until you realize they are just a bunch of really, really stupid, inept, confused, probably insane, brainwashed, morons with a poor grasp of reality and basic literacy.
You're more likely to die on your toilet.
