I was talking to this older lady today outside the building

[MiniMe]

She asked me if I was a Barack supporter. I told her I was the democratic nominee supporter, which is true and why for the most part I have avoided GDP. She started telling me that Barack is racist. I said, No, he isn't. What makes you say that? She said from his speeches a year ago. WTF? Where is this crap coming from? I really don't understand what makes her say or think that Barack is racist. I have never heard this talking point before and I want to have some good comebacks. Can anybody help me understand?
