That's not very well... Christian Phil, to insult Jac like that especially without him here.
Jac was passionate, as we all are about our particular beliefs. And, if he disagreed, he was straight up rather than being around the bush. He was quite masterful with his rhetoric, and by that I mean art of effective and persuasive speaking including either sly or good insult (in order to persuade and try get people on side while rilling his opponent) -- that wasn't nice to be on the receiving end of. Sometimes he didn't like it back and then it'd go to the next level.
But, it seems to me fair game, and certainly made for interesting discussion and reading to those following.
Despite any disagreement or falling out, I still have a great respect for Jac.
