Absolutely false, and I have no idea where you're getting this from.
Here's from their website:
"We are committed to embodying and practicing justice, liberation, and peace in our engagements with one another." --

That's their website. Of course they aren't going to admit that they are a fabricated group designed to help divide america.
I am getting this because I keep seeing the same patterns over and over. What do they talk about the media? Conflict. With whites and blacks, Muslims and non-Muslims. Trying to make you think that a certain group is to blame, when it's all being fabricated. This is not a conspiracy theory, this is an old trick that has been done before, where groups and entire nations have been divided.
There is a serious divide and conquer mentality going on and this affects every single one of us. Druids, Muslims, Zoroastrians, Jews, Christians, Whites, blacks, asians ect.
