I was just responding to YOUR semantics complaint over Caldera's use of the word.  

But you're right that not all hot markets gentrify when new landowners buy old ones out.  That gets more into the racial and social makeup of the people moving in vs the people moving out.

Surely you're not suggesting government should put racial restrictions on who can buy a house, or who you can sell your house to, are you?  It's still a free country.
