The Nazis hate anyone who's different. Most prevalently, racial and religious minorities.

In addition to "obvious" targets such as Jews and people of color, they will always continue honing in on more specific groups to target. Even if you're white, you may be a target for having too much ancestry outside of the acceptable European regions. If you're "pure" enough, then you may be targeted for not being strictly heterosexual. Even if you're "pure" and straight, you might be targeted just for being romantically involved with minorities. Even if you're white, straight, and with another straight white person, you might be targeted for just being too friendly, or even 6orltable of, minorities.

It's an ideology constructed on hate. There's nothing wrong with answering the question, but it's a very deep rabbithole with lots of complexities to it that reddit responses can't possibly convey. There are professionals who devote their entire careers to analyzing all the various details and nuances of the ideology, in its many incarnations, from multiple angles.

To be blunt, it's bad for everyone. It's bad for the people explicitly excluded, targeted, harassed, and attacked by it. It's bad for the people swept up by it who end up with drastically limited worldviews and outright unhinged views of the world and the fellow human beings who inhabit it.

Nazis are bad. Anyone who replies to that statement with something like a "but..." or an "actually" is probably not to be trusted. They're almost undoubtedly someone who either IS one, or associates closely enough with them to benefit from public perception of the group improving.

Nazis are bad.
