Is it good to have cultural diversity?

Yes and no.

Yes in that in an ideal world that's how things should be.

No as in no cultural differences in any area tend to set up little 'enclaves' where one section (often referred to as a 'community)is deeply mistrustful of any other !

It really is. With cultural diversity you can have pizza and Chinese food at restaurants within one block of each other. You can wear an African caftan and be comfortable when you are at home, you can wear flip flops without being Japanese. Other than that, and music cross-overs, I am seeing more diversity in anger and rudeness.

Yes. I grew up in a community with no diversity at all. It wasn't until I moved to a different state, very diverse, that I began to really understand other people from other cultures. I cherish my cultural background, and I expect others to do the same.

its a melting pot of PC overload and bullshit

Generally, yes. I mean, it depends on what you want it for.

Yes

in a word? Yes.

Anyone who disagrees is obviously a trump supporter.
