That's kind of a silly argument (Harlem's 50+ year residents were most certainly in Harlem during the race riots), but regardless that wasn't really my point anyway.
The incoming community always brings their culture with them, with very little incentive to preserve the existing culture. They have no reason to keep a Murry's around - they want a Whole Foods. The Russian Orthodox cathedral looks cool, sure, but a new luxury high-rise could be built in that spot instead.
> IMO, current residents have no more of a right to live somewhere than any newcomer.
That's also not really the point. It's not about who has a right to live where. It's about making sure we collectively don't tread over artifacts without taking a step back and evaluating what we're doing as a society. By the time we decide something has historical value and should be preserved, it might be way too late.
