Pseudo-intellectual justification, especially for not taking your own side.
 
Attacking (publicly, not criticism) those on your side because they made what you see as an error.

Cowardly Disloyalty.
 
Circuitous refusal to accept the obvious
 
Following letters rather than spirit, not seeing that people trying to weasel around something are trying to weasel around it
