These muslim women are already in contact with these groups. They are in total agreement with each other. These groups have always hated christian heterosexual males and non-socialist America.

It should fractionalize the Left, since they don't want to be seen being too chummy with the enemy, but they don't want to take an opposition position to the enemy either. It would be fun to see them dance around.
Of course, if women representing the enemy spoke to leftist organizations in the U.S., the press would find other news items more worthy of coverage, and bury this as a story.
