I actually totally agree. All people should begin worthy of our respect simply because we are humans, and our language should reflect that. Where the break is for me is that (again, for me) honorifics and similar terms imply hierarchical respect or deference, and that’s where the “earned respect” comes in. My respect for you as an equal is yours to lose; my respect for you as superior is yours to earn. In my language community, regular old please and thank you communicate the first kind, while honorifics convey the second.
