Jim did not just disagree with me about the signs, he said I was lying.
The second thread forced him to retract the accusation (a first) and proved him wrong.
His refusal to admit being wrong made him look silly.
Why does he do it?

On the over-rep, he did not just disagree, he said it made me a racist.
Now everyone knows it is a fact and his continued denial makes him look silly again.

I am done with both.
