It's their same old trick: Take something we know the conservatives disapprove of (but we love) and then blast one of theirs for hypocrisy when we catch one doing it. According to Hannity one time with a good insight, the only moral value they seem to have is that against hypocrisy. Just as Coulter pointed out the only constitutional right they seem to care about is dissent.
IOW, when one of theirs does it, it's just what they do, but when prissy Laura Bush does it, oh the Horra!
Exactly.
They are using the old double standards technique for 2 purposes - divide and conquer and proving their stereotype of conservative cristians as uptight moralistic prudes - and they are doing a good job.
