What if I don't believe in the inherent worth of human beings?

What if I believe some people, like Nazis, are worth less than non-Nazi human beings?

Ableism is bad. I'm just not sure that 'inherent worth of human beings' is the reason to oppose it. Some human beings, like Nazis, have qualities that legitimately reduce their worth. Other human beings, like the disabled, do not inherently have qualities that reduce their worth.

The question is less about inherent worth of human beings, and more about what qualities are legitimate to judge a human being on.

Ableism is also, in my opinion, one of the more insidious types of prejudice because it frequently underpins other forms of discrimination. For example, if you ask someone who is racist why they hate a particular group and it's often because they believe that group is not as intelligent, or because they can't control their emotions or behavior. Those are inherently statements about a group of people's abilities.

We spend a lot of effort dispelling the misconceptions that those groups are less capable, but for some reason there's substantially less effort that goes into dispelling the misconception that someone who is less able to do something is less worthy of human rights.

And that's not to say that individuals who have shown they're genuinely dangerous to others should be allowed to cause more harm, it just means that they should be judged individually based on their individual actions and not treated with cruelty.

or even transcend "worth" judgement entirely, and just have respect and compassion.

You say ableism, I say more than that, the worth of a person being defined by how much money they have or value they can produce for others.

But you are probably on about removing every negative word like stupid, moron, idiot? Road to perdition my friend.
