It seems to me this is a personal bashing issue, not necessarily a Bush bashing issue. I see no problem with spirited debate as long as it stays clean. If it doesn't, then the high sticker should get a stint in the penalty box, no matter what side they are arguing.
BTW - I see red flags coming from both directions.
So do I! Both ways is right! You can debate and stay civil! That's what has been missing IMHO!
