From what little I heard back then, yes, I defended him to a degree.
I've said it time and time again, I wasn't as involved in politics then as I am now nor did I have as much access to the various media sources that I do now. The latter is why I've become so much more involved in politics since 2007 - information access! So, although I was privy to some of the distasteful things that were said about former Pres. GW Bush that were espoused on network TV (ABC, NBC, CBS...again, limited access to political info back then), I wasn't aware of how wide-spread the hateful discourse was concerning him, his policies or his political views, and I my dislike for him certainly didn't improve once I learned how he and Tricky Dick2 (Dick Cheney) tried to hijack the judiciary. (You'll have to read the book, "The Return of the Imperial Presidency" by Charlie Savage to understand fully what I'm referring to.) However, I will honestly admit that although I did vote for him the second time around in 2004, I didn't agree with many of his policies. But as has been said concerning the choice between McCain and Obama, I didn't think there was much of a choice between GW. Bush and John Kerry. Besides, I believed that it was important to keep Bush in the White House since the nation was involved in two wars. IMO, it wasn't right to throw that in someone else's lap.
So, to answer your question (which tends to come up every time someone speaks out against the talking head's slanderous anti-president "free 'hate' speech"), yes, to a degree I did stand up for GW. I may have disagreed with his policies and attacked same, but I've always respected the man who held the Office of the President of the United States, and would defend him whenever I heard someone attempt to slaunder the man himself. You can talk about the President's policies and what you think he's doing wrong all you want, but slander his name, i.e., to call him a Nazi, a traitor...things like that..., I stood up for him every time I heard stuff like that. Now, if folks called him a liar for the testimony given before the U.N. which he supported as justification for going to war w/Iraq, yes I called him a liar and still do to this day because evidence and events since then have shown him to be such, i.e., no WMD of the caliber his Administration testified were present in Iraq were ever found. I didn't believe in the Bush Doctrine either. But I never called the man out of his name, nor would I show contempt for the office he held by not addressing him by his title, "President", and would rebuke people I heard do it then just as it tics me off when people do it to President Obama.
Hate the policies, dislike the man all you want, but don't disrespect the Office he holds nor the title given. Give him his proper respect. It's "President Obama", not Imam Obama nor the Messiah, or any of that other crap. I took the very same approach when G. W. Bush held office....and Clinton and Bush, Sr., and even Reagan.
