Notch Believes there are white people who think Racism doesn't exist.
That Racism very much exists.
Your poll is still asking the wrong question. It does not, in any way, refute Notch's opinion.Notch however thinks white people are in denial that racism exists.
If I said, "There are some people who believe men never landed on the moon."
You could not disprove my argument by asking some on here if they think men landed on the moon. You would probably get a 100% affirmative response.
But if you asked the correct question, "Do you doubt that there are some people who believe men never landed on the moon?" You would get a 100% negative response.
So if you want to pursue your own agenda, then do so without using Notch's opinion as a springboard, because your poll and his/her opinion are not connected.
However, if you want to disprove Notch's claim, you need to address your poll questions.
The 3 respondents who believes that racism does not exist, absolutely proves that Notch's opinion was correct, i.e. 3 out of 19 equates to 'some'.
