This is a very important observation. I wonder the same thing. Christian institutions can be very dangerous places for ID dissenters. It is risky to challenging the ID establishment, as they are not okay with people who break ranks, or at least that is what faculty at these institutions have told me.
That is exactly right. Most of the key players in the ID movement are on the way out. This is true for both ID, YEC, OEC, and New Atheism. Yes there is exceptions. Most, however, are from another generation.
There is a new generation of scholars rising that wants to find another way. For those that have been in the center of this mess for the last 10 to 30 years, helps us find that better way too. We could use the humble guidance of leaders that can show us how to do better then they. If that is not a shared goal, maybe just get out of our way.
