Does a person’s beliefs make them good or bad?

For instance, if someone’s religious or political beliefs don’t line up with your own, does that make them a bad person or a stupid person in your opinion??
Would that be the end of trying to understand the person, or would you continue to interact with them on other topics?

I would hope most people wouldn’t label someone so harshly simply because they have differing opinions/belief systems….but sadly, it seems to be a common practice…?

Especially online….?
