Then how am I supposed to debate?
Obviously you would prefer I did not challenge your precious dogma.

We started to discuss this major news story, and Lox and later you said it was not true.

So I post a quote from a reputable person whose experience is that it is true.
You still deny it, so I find another, and so on.

And that makes me racist?

If you did not deny the experience of every witness I put up, and every bit of hard evidence, I would not keep putting up more.
