I don't think it is possible to separate a person from their ideas. You are the sum of your ideas. If you hold a bad belief, that is a bad piece of your whole personality. None of us are perfect. We all have bad ideas sometimes. That means nobody can be an entirely good person. But the converse is possible; we can separate the idea from the person. And when judging the merits of the idea, we certainly should. Consider that if you separate all the ideas from a person, what is left? An empty shell of a body? Does it still have a person in it?
