Dammit, do I have to throw away all my straights and only DE and go buy a 5-blades-cartidge Gillette whateverthefad (TM) ? Am I that mistaken? They vastly outnumber both DE and straights after all. That must be true.
That's the gospel to which I adhere
I have no opinion regarding the rest of your editorial, since I do not feel much included in these definitions of shaving, except for the "sharp specialised blade to remove the hair without removing the skin"
But then again, in my case it's less about hair, blade and technicalities (that's what I do when I'm NOT shaving) and more about having a pleasurable time taking care of myself and my manly needs. (*)(**)
(*)Priming for greasy jokes intented, keep them as edgy as your razors folks
(**)I mean except for the 10mn after you stop the car and before you get inside, it's the only real "me time" a grown man has
