I'm not even sure this is truly a racial issue for most arguing the issue. If this decision and this press release occurred 10 years ago, nobody would even blink an eye. If it occurs 6 years ago, nobody would blink an eye. If this occurred 6 months ago, no one would blink an eye. However, with the decision coming immediately after the events in Virginia, this Is now an "us vs them" issue that gets caught up in the political divide that this country is going through. Now it is seen as the Dems/Libs "winning" so the right comes out against it. If it was the Repubs/right that made this decision, the left would come out against it just as hard.
Politics in this country is gang warfare right now; too many people don't have a side until they find out what side "their" party is on. Both Parties flip-flop on issues constantly while catering to their extremes in order to generate money to keep them in business. Neither party truly cares about legislation and true compromise that helps the country and its constituents; both just care about "winning" and drumming up outrage over petty issues ensures that no one is talking about what actually matters. Basically, the politicians on both sides get rich while everyone else suffers.
It really is too bad that our political system doesn't really allow for more than two parties and more than two political viewpoints.
