The excellent and fairly new website Death Roe.com has as section on Roebots.
Roe•Bot \ro-bät\ n (1973) [American] 1 : a self-delusional member of the species homo-sapien with the ability
to substitute basic human reason and morality for brain-dead devotion to Roe v. Wade 2 : a man
or woman characterized by an unlimited capacity for ignoring proven biological realities while chanting
the pro-abortion "party line" 3 : someone who can mindlessly, and without question, regurgitate totally
discredited arguments over long periods of time.
Good definition to go with my previous parody Attack of the Killer Roebots.
