What does it mean by respect cultural diversity?

Cultural Diversity is a term referring to the differences between opposing cultures. Culture referrs to customs or traditions (inclusive of religion in my opinion) that are genuine to a certain area. So what about the respect of cultural diversity? Disrespecting cultural diversity is like a Christian insulting the Jewish holiday Honica. Although a Christian thinks differently (in terms of faith, belief and religion) as a Jewish individual, having a respect for cultural diversity would be not to deface their religion. Instead, accept your differences, follow yours, and let them follow theirs. Having a better respect for cultural diversity would make the world a better place. :D
