I've been hearing people talk negatively about vocal fry for ages now with no idea what it meant. But this comment was finally the one that made me go look it up. And today I learned that I speak almost entirely in vocal fry.
I think there's a generational judgement part of it, and some hearing damage that makes it harder to understand their words on the very low/creaky end.
Not to mention, it can cause real problems for your vocal chords. A little bit is entirely natural, and I don't really notice it in most men, but a lot of young(er) women seem to go overboard on it (in my opinion).
