Gravatis is a fake news, made up liberal garbage Word propragated by idiots. When i see that used its immediate dismissal...
Latin teacher here. Gravitas is Latin for the idea of taking something dead serious because it deserves it intrinsically. You are using the idea yourself when you say that you immediately discount any user of the word. For you the user of the word has no gravitas. You may be right about this, but don’t listen to me cuz don’ nobody take me serious.
