I could refer it to the right wing in general, but to be theologically correct,
Proposition: With the exception of their own parents, many children of the religious right love to grill the religious right.
With this proposition, I take it that their parents must at the least level of their hearts be disappointed at their children, in spite of the various masks the parents are putting up. Not because their children are not as extreme as they are, but that their children are irreligious all together.
Thus, the slightest change or opportunity for their children to inherit some portion of a devotion to God, even by mere appearance, should cause a burst of joy in the parents.
This is not surprising, that certain emergent churches such as that of Tim Keller's, that maintain conservative orthodoxy, are much appreciated by these parents when they learned of their children's involvement in such. Nevertheless, the shallowness of theology even among such parents, does not serve them any better in any further analysis of such churches more than what the media are saying.
Beyond the superficial admiration of these deep American root parents at celebrities such as Tim Keller, it imperative that they should truly admire those who are able to influence their children truly in a doctrinal praise and worship to God, regardless of race or fame, which often get in the way of such admiration.
On the other hand, we can command sympathy from the scornful towards these parents because of their children.
