Only in a court of law. Look around, this is not a court of law.
Are ALL "baseless claims" lacking "proof"? What is the "proof" that the Flo-jo "drug connection" is a "lie?" Something you've chosen to believe.
Again, that's only in a court of law which this is not. Stating that FloJo was clean is just as much of a claim as stating that she was dirty. It is up to the proponents of either side to provide evidence (notice I didn't say "proof").
You're accusing her of being clean, why do you believe in such a claim?
