Sporting different color magnetic ribbons or bumper stickers that say "Free Tibet" on your car. It may be a "support our troops" yellow ribbon, a pink breast cancer ribbon, or any number of preposterous incarnations meant to capitalize on this trend. When you put stickers and magnets on your car, you aren't doing anything to support the cause. Thus, inactivism.
Julie has a "Free Tibet" sticker on her Subaru. But she hasn't done anything to actually help free Tibet. She also has an orange-spotted green ribbon that supports narcoleptic dogs. This doesn't do anything for narcoleptic dogs. This is inactivism.
