If this is as horrible as some people are making it out to be, than future generations will look back at it and shake their heads while my opinion remains in the shadowy corners of my own mind (and this internet forum).
Right, but why wait, if it is something legitimately terrible i.e. the Woolworth's counters? To simply wait and let history decide what was terrible does nothing for people who are being affected by such issues at the moment. We're supposed to let them be martyrs so that history can look back in 20 years and say "oh yea, that's wrong" or we can do something to address the issue as it arises?
I don't necessarily think that this is the case with the issue at hand (although the mentality that some don't want to interact with "poor people" or whatever coded language you want to use is despicable yet hardly unsurprising and sets a bad precedent, for sure) and seems to just be stirring a big pot of internet outrage but the argument that "they own the building, let them do as they please" is incredible dangerous as history itself (!) has shown. If we're supposed to learn from history, why wait again to see what "history decides" or whatever?
Important issues, like segregation, need real action - not a prolonged public relations campaign.
