[quote=spdrun][quote=CA renter]We prefer to have different cultures, governments, economies, etc. so that people can choose something other than what they currently have. Migration has always been a part of human history, and I would never want it to be otherwise, but eliminating borders and consolidating governments, currencies, trade rules, economies, religious preferences, ethnicities, (even races) etc. is not a positive thing, IMO.

Open borders won’t eliminate diversity in the way that you’re thinking. The US is very regionally diverse, yet has open borders between states.
The EU is also reasonably diverse and has open borders for citizens of any EU country. European borders were also practically open between the Napoleonic Wars and WW I.[/quote]
People tend to congregate with others who are similar. It’s perfectly natural.
But open borders are indeed erasing regional differences. These days, it’s much more difficult to tell if someone’s from Texas than it was ~30 years ago. The accents have largely disappeared, and the cultural differences (if you can call it that) between states has been muted.
The Europeans are worried about losing their national and cultural identities, too. It’s 100% natural, and there is nothing wrong with that. People can call it nationalism (not saying that’s a bad thing), or even racism, but it is as much a part of human nature as greed and hoarding. It’s a survival instinct.
