La_chica_gomela, you have clearly never studied linguistics if you don’t understand what “descriptivist” means, and the contrast with “prescriptivist.”
See how asinine that sounds? It’s probably best if you stop assuming what I have and have not ever done simply because I disagree with you.
Further, it’s probably best if you stop the dictionary-thumping now, because you’re trying to use a descriptivist tool to make a prescriptivist argument, and thus you are not likely at all to convince me, and if you continue it’s only going to reinforce my assessment that you don’t grasp the distinction between descriptivism (which you seem to heartily endorse) and prescriptivism (which seems to be an alien concept to you.
Further, consider what happens when you have three related words with different shades of meaning, and what happens to the richness of language when people who don’t know any better use them interchangeably. Consider insure/ensure/assure, infer/imply, accept/except, flaunt/flout, and the like—what happens to the language when careless and ignorant people use words incorrectly? It is greatly diminished, and all in the name of a foolish populism.
Carry on thumping your dictionary, if it makes you feel better; just don’t expect it to convince anyone until you understand the logical fallacy you’re dancing around.
