So what do you propose doing with those you regard as 'worse'?
I think your view leads to a sinister slippery slope.

I'd say, it doesn't make them worse, it just means you disagree with the group they belong too. And otherwise you are equally human beings with human rights. (Of course, a person might think that to be wrong is a verb that only exists on the third person, and to be right, only in the first?)

Forgot to mention that the Mormon lads refused tea, and offered to hang out my washing for me--which I refused. And they didn't utter a word to convert me.
