I need some help here!

I am on Twitter and there is the famous topic of Ron and Rand Paul being racist again!I am getting sick and tired of this!How can someone be racist if there are for individual liberty?!Now this person is saying they had a personal experience with Rand and Ron using the N word with there attorneys!I don't believe it but I am really starting to get pissed cause if this is the only thing they the establishment can come up with!I have ignored them and proven the letters were NOT written by Ron Paul and given the video with CNN!Help would be appreciated!
