Smart. Move. I dont have a problem with whites marching but they do need to recognize this is a Black issue and should be Black led. Too often letting whites in positions of leadership for Black causes either makes us look weak or creates a convenient spy network.
Yeah dumb ****, let them lead then. Leading is more than where you stand in line physically. The lady is only showing her insecurity, NOT leading, again this shows your small minded view just like hers. If you have to tell a white person to stand in the back of the crowd in order for you to assert your leadership you've already failed.
A good leader unites people, creates commraderie. A dumb **** sows bad blood and mistrust among the people.
Of course you just dont want white people there. Just tell them all to leave and be done with it.
