When a sane human being (neither of which you are) accuses someone of lying, they reference the lie.

First, I have yet to make any positive statement about the current president.

I have made several negative comments, ALL TRUE, about the previous president.

What is it about exceedingly poorly educated things, such as you, that cause you to tell bald faced lie upon bald faced lie?

You poor, poor, pathetic little thing.

I truly pity you.
