That's usually the attitude I try to take. I'd promised myself he wouldn't bait me...and I reisted for over an hour of constant sniping about "what are moral values?" "I only ask because that's what a lot of "those people" voted for". He'd get no response, then 5 minutes later he'd whine "It's scarry...my rights are under attack". He'd get no response.
Finally after about an hour of this nonsense I responded. And we were off...
I need to learn how to ignore him. I think that would bother him more. I wish I could just walk away but we work where that just isn't an option.
