Your point is actually two:
1. Debating with me is pointless.
2. I don't believe in facts.

point one is dependent on the validity of point 2, so I'll begin with concentrating on it first.
I believe in facts, though very few:
a. I believe in most Axioms
b. I believe in a priori knowledge.
c. I believe in Empirical knowledge

I'm sure there are more, but these are the big ones. So to say I don't believe in facts is false, therefore point 1 is by derivation false, and the main point submitted is also.. false

Maybe the author of the point could give some examples of "facts" that I don't believe in.
