The issue is not whether or not he had anything to do with it. You stated, "he wasn't in any way called "racist" by anybody until he ran for president."
I gave evidence from a 2011 article that has a number of links describing how he was involved in things in the 70s that would make someone call him a racist.
"Would", if he ran for president against a democrat back then. As things stand, the article you linked to doesn't directly call him anything of the sort.
