I am a free American citizen. I get to label anything that I want to with any label that I want to. With a little luck, that will become the label that everyone uses, and earlier ones will be forgotten.
While I admire this quintessentially american sprit--what a rugged independent cuss you are--it doesn't really help much in addressing perplexing questions of the Commons, such as mandatory universal public schooling. Like humpty dumpty, a word means whatever you want it to mean? That works great until you are engaged in cooperative, reciprocal communities. Then, suddenly, objectively sharable meanings arising from historically commmon context and usage become vitally important. It is not useful for science to mean whatever you like, however much that tickles your fancy.
