societal camouflage
Any act of deception preformed by an individual or group with the intent of concealing beliefs, attitudes, wealth, position or situations which their peer group, local community or society at large may find objectionable.
Societal camouflage would describe a family of athiests that send their children to Catholic school to avoid being stigmatized by their neighbors. Ex. Eric is gay, but is married to a woman so that his conservative employers will accpet him.
