Most of them were in fact NOT Christians, You can find thousands of Strawmen to beat up on this issue, but if you look hard enough (past the Register Guard website), you can find some Christians educating other Christians on this subject. Gregg Frazer is a Professor at Masters University and gave a few lectures on this subject a few years back debunking David Barton, you can listen to it here. Now I am sure a staunch Civil Rights advocate and crusader for justice such like yourself would be willing to give it a listen and let everyone know your findings, wouldn't you Chuck ? That would be the right/fair/just thing to do, wouldn't it, Chuck ?
