Serious

Chait does a nice job of breaking down the symptoms of acute neoconservatism.

The interesting one is "serious" combined with all the other traits.

Neo-cons refer to their political opponents as "unserious" and that "serious" people agree with them.  Perhaps a better word than serious would be severe.  Because there is little that is serious about the half-baked, knee-jerk, simplistic way that neo-cons see the world.

Neo-cons can't make threat differentiation; they can't distinguish Sunni from Shia or Wahhabist from Alawite.  All they see is "bad guys" who must be addressed with violence.

That's a profoundly stupid, cloistered way of looking at the world.

It is the exact opposite of "serious".
