Military vs Civilian Orbital Laboratories, Vehicles, and Crews

1) Some people imply that the space shuttle and its support structure
(like the Manned Orbital Laboratory) was designed from its inception
to accomplish military goals.

2) Since the Challenger disaster with an IUS aboard, the space shuttle
has been deemed too dangerous for non-astronauts.

3) Yet military advocates don't blame the Air Force for what they
consider our civilian space shuttle / space station dilemma.

How is it logical for advocates of failed military orbital
capabilities (manned) to denigrate our current civilian orbital
capabilities?
