Question

Why do you think certain culture deplore one another???

Answer 1

It's not their beliefs, so therefore they think it's wrong and shouldn't exist.

For example, crime. As you're growing up, crime is meant to be bad and you shouldn't do it. This is the same for cultures. You grow up with that culture and are taught that's how things should be. So when you see another culture you think it's bad and that it shouldn't exist.

I hope I could help!
