Someone who tries to stop the progression and evolution of the human race by urinating on freedoms, destroying equality, pushing their morals on everyone else, going to war, and polluting.
Antiprogressors tend to like to either reuse old ideas that failed years ago or reuse old ideas that worked a thousand years ago but would never work now.
Antiprogressors also tend to always be at war with something (no matter how ridiculous it is). They are often at war with elicit drugs, petty crime, non-existent terrorists, and the scientists/intellectuals who try to evolve and progress the human race.
Basically, a republican or a conservative
Stephen Harper is an antiprogressor just like George W.
