Eyewitnesses and also at least one media report from a black community newspaper in Houston. I don't think Barton was doing as much of the shaking in the aisle like Weddington, but he was definately at some of them. I also believe he gave some sort of "historical" talk during the meetings on how Republicans are the party of civil rights.
GOPcap,
It's quite possible that Barton and Weddington had no idea of the spirit-animist origins of the "slave kettle". But the black ministers who were there will have known, and if they didn't tell their guests what they were dealing with.........
BTW, as I mentioned to you in my FReepnote, the freedmen and freedmen's sons who built houses in Third (and/or? Fourth?) Ward also did the brickwork in the streets. At certain intersections where the original brickwork is preserved (identifiable by the very high-quality, large and heavy "paving bricks", as opposed to the mere house-bricks with which the City pretended to repair such pavements later), the workmen laid patterns in which the Yoruba cosmogram that I described to you is represented in sketch-form. And the location of the cosmogram photographed by the lecturer I heard was right on top of a water-main, thus satisfying the other requirement of such signs, that they be located near water "of some sort".
So some of Houston's streets preserve pagan African symbols in their brickwork.
