This response is more to the original post, but I know what you mean. On the one hand, the President has spoken about a trial. If you speak about one, there could be hundreds or thousands of others that deserve comment, but he didn't, and shouldn't. On the other hand, he is the first person of color to be President. If he can't be involved in, or lead, a discussion of race in our country, then who can? I think he could have been more diplomatic or less removed, but the president is a person too. I think it must be difficult for any president to be personable and be a leader at the same time. Carry on.
ETA: I don't think the president should lead discussions about race, I misspoke. But I don't think that as a person of color, he should ignore it either.
I believe all news and research that supports my opinion, and dismiss the rest as conspiracy and lies.
