Maat, it is all here to be viewed - Farrakahn has been quite explicit in his condemnantion:

To President Obama, Minister Farrakhan delivered a pointed warning: “Don’t let these wicked demons move you in a direction that will absolutely ruin your future with your people in Africa and throughout the world. They don’t like the way you handled (former Egyptian President Hosni) Mubarak! They don‘t like the way you’re handling the situation in the Arab world! So I would advise you to be careful-and move with wisdom and skill.

And then, Minister Farrakhan offered President Obama some divine advice.

“Why don’t you organize a group of respected Americans, and ask for a meeting with Gadhafi? You can’t order him to step down, and get out-who the hell do you think you are, that you can talk to a man that built a country over 42 years, and ask him step down and get out? Can anybody ask you? Well, well there’s a lot, now, [that are] going to ask you to step out of the White House, because they don’t want a Black face in the White House,” said Minister Farrakhan.

“Be careful, brother, how you handle this situation because it is coming to America! It has already started. Look in Wisconsin! Look in Ohio! Look at what’s going on in your country! And remember your words because the American people are rising against their own government: It’s not Muslims; it’s not Black people! It’s White militias that are angry with their government, and they are well armed. Are you going to tell them-’Put your arms down, and let’s talk it over peacefully?’ I hope so. But if not, America will be bathed in blood, not because Farrakhan said so, but because the dissatisfaction in America has reached the boiling point. Be careful how you manipulate the dissatisfaction in Libya and other parts of the Muslim world,” he warned.
