Not one response...ever!
Over the years I've been able to maintain a cordial correspondence-via the Internet-with writers of divergent viewpoints, everyone from noted Israeli conservative pundit and scholar Steven Plaut, to the author of the "Chatterbox" column in Slate, to even that egotistical, H.L. Mencken wannabe who pens a regular column for the Newark Star-Ledger.
However, for some undisclosed reason he doesn't see fit to communicate with another member of the same website.
Go figure.
