I think in this case it's used in kind of an "I'm a member of an exclusive club" with a (possibly subconscious) emphasis on "exclude".
I am reminded of "Acronyms Seriously Suck" (Elon Musk memo)
I didn't mean to communicate that, but your point is fair nonetheless. In my defense I think I was inclined to use the acronym "DE" because I had already read through the existing comments and had seen other discussions already taking place about double-edged safety razors and referring to them as "DE" so I kinda switched to that "in the club" mindset without thinking. My apologies if you'll have them :)
