Voluntary diversity is a good thing.
Forced “diversity” is disastrous.
Forced anything is.
Forced “charity” is theft. Forced “safety” is slavery.
Recognizing the disastrous nature of forced diversity isn’t justification for government “borders,” though, because forced division is just as harmful as forced diversity. Government’s involvement can turn any idea into garbage.
Anything government touches turns to crap. Good thing government won’t touch liberty with a 10-foot pole!
