Legal and common definitions are often at odds. Legally, marijuana and cocaine are "narcotics" but pharmacologically they are not. The law defines personhood for biological entities too. One minute before birth, it's not a legal person. One second after birth, it is a legal person. This is nothing new. If you don't like the law, convince enough people that the law should be changed.
