While I don't doubt your veracity coluber, I find it impossible to believe that the people you heard on that radio show are a representative cross section of Texas conservatives.
However, there is not necessarily an inconsitency in the positions you've described.
On the day of the Superbowl, there wasn't a parent in America who had any notion that a bare breast would pop out on the TV screen their children (of all ages) were watching. Janet didn't advise the audience that at some point in the show she would be releasing one of her twins and thereby offer them the opportunity to shield their children from the sight if they so chose. The fact of the matter is that Janet Jackson couldn't care less about whether or not there were children watching her spectacle or whether or not the parents of these children wanted them to get a look at her boob. Whether or not any kids were actually scarred by the sight is immaterial.
I seriously doubt that many, if any, of the presumed conservatives whom you heard on the radio endorsed the idea of their children viewing the Nick Berg video. Suggesting that showing the video to children who had their parents' permission would have been OK, is not the same as saying that the video should be shown to children.
Contending that parents and not state institutions or entertainment conglomerates should decide what is and is not proper for their children to view is a consistent conservative position.
I have a suspicion that you believe conservatives may be generally in favor of showing the video to children because it reinforces the need to have our troops in Iraq. Out of curiosity, what do you think the political persuasion of the two teachers is?
There could be a tremendous irony here because I know my conservative friends and associates (as well as myself) have assumed the teachers were liberals who believed it was necessary to show children the horrors of war so that they could appreciate it's true nature and resist it.
I wonder if anyone in this forum knows for certain why the teachers felt the need to show the video.
By the way, under any circumstances, the last line of your posting is perfectly ridiculous.
