I dont get your point about Sharpton and Jackson. They draw crowds on the issue they speak out on because people are concerned about them. that doesnt make them leaders of every Black person.
So you don't consider a unarmed minor being shot by an adult playing cop and not going to trial to be a significant enough issue to warrant the POTUS commenting on it? Its a good thing what you think doesnt matter. There should have been a trial and it happened. Tough that it bothers you that Trayvon could have been his son. What exactly was the problem with that statement?
Whites kill off whole civilizations. Please dont try and preach to me about who is more violent. You only look stupid.
The mainstream media is in no way pro black. Where did you dream that one up?

Sharpton and Jackson get coverage because the media knows it drives white racists ape shit and creates ratings. You really need to educate yourself about the world you live in.
Only the ghettos are in a deplorable condition. Not all Black people live in them. Stop believing what the "pro-black" media tells you.
You are delusional: Trayvon layed in wait, and attacked Zimmerman, and tried to murder him. Your black victim mentality won't allow you to accept the verdict - too bad. For the record: I don't give a shit about either. That case was insignificant ( except to race baiting victim minded blacks, and their controllers ) Minors murder people all the time - see Belton. Trayvon was armed with concrete, and fist. Both have independantly been proven deadly.
If you can't decipher why the POTUS should not takes sides in a racial case, and even comment on a single case which is insignificant, you don't understand what that position is all about. I ask you now: why does he not claim that murderous blacks could be his sons, or why " Shorty" Belton could not of been his dad? He is racially divisive!
The mainstream media magnify white on black violence, and won't even identify the race when it is black on white! I said that they promote themselves as pro black, but they are really anti black - as they feed you your victim reinforcement diet.
Blacks on this globe treat other blacks more savagely that whites. Black on black violence is hushed.
You really need to accept the facts, and purge your mind of the polution that has inculcated it.
The black race is in a way more sorry state than others. Instead of casting blame elsewhere, your race needs to assume personal responsibility; identify your weaknesses, and work on them - they are many!
