I'm sympathetic to that viewpoint but as the sibling comment pointed out, America is 76.3% white. If the push is "remove all the divisions, everyone is part of one group" then the interests of the majority within that group will dominate.
I believe that 76.3% includes hispanics, and hispanics are considered a minority. When people talk about whites being the majority, my inclination is to assume they're talking about non-hispanic. That lowers the percentage to around 60% or so (I'm not sure on that number); still a majority, but not as much so.
