Joe,

I speak from experience here, even if it is do what I say not do what I do. Let it go. If not, you risk embarking on a long and increasingly unpleasant dialogue with a person whom you seem already to suspect of not reading your posts properly before responding. At least he hasn't called you a racist, like he did me.   

Anybody worth caring about will have read your contributions and will think fairly about them.

Best wishes
Pseu.
