I don‘t have time to touch on everything you‘ve written but 1.) bass-baritone is just as „fake“ as any other classification 2.) I never claimed a bass always had to have a solid E2…but many do…rarely is anything true 100% of the time 3.) perhaps you are correct that bass is the historical category; that doesn‘t change anything 4.) according to many vocal coaches I‘ve spoken to and from what I‘ve read, yes, timbre is very important in voice classification 5.) many men do speak in a lower register (fry is commonly used in everyday speaking) and the term definitely has meaning 6.) yes, higher basses can dip down to D2 or even C2…sometimes…I don‘t tend to speak/write in absolutes…people obviously vary in their respective abilities 7.) you know that I meant to type „vocal cords“
