I don't know...I once admitted that I agreed with him on ONE issue, and he used that for his sig for weeks.
But madam, one has to separate the internet-created
persona from the real person.
In real life, John C. is known as a loving husband, a respected father, an admired neighbor, an esteemed friend; generous, compassionate, caring; a credit to his race.
On the internet, he purposely comes across as an old grouch because he doesn't want strangers to take advantage of his good nature, his good will, and his good wallet.
One can't blame him.
