Bull.

Someone shoots me in the chest and kills me. My right to life has been taken away from me without my consent. Sure, maybe I should've been wearing a bulletproof vest when I went down to the market to buy a gallon of milk. But I didn't willingly "give up my rights" by leaving my house without a flak jacket.

Someone breaks into my house and steals my TV. My property rights have been taken from me without my consent. Sure, maybe I should've hired a full-tme security guard to patrol the house. But I didn't willingly "give up my rights" by deciding not to hire a guard.

My boss fires me because my skin isn't the same color as his. My civil rights have been taken away from me without my consent. Sure, I could always file suit in court, claiming discrimination. But my failure to do so doesn't mean that my rights weren't violated in the first place.
