Dancing Around the Four Sides

ask a detailed question about phonology, such as "Do you really pronounce 'tr' as 'chr'?" (Yes, yes we do. We all do. It's almost impossible not to due to the physiology of those phonemes.)

And this will generate a burst of absolutely, frustratingly useless nonsense, because people just do not know how they talk. They don't know how they talk, they can't analyze their phonetics on the fly, and they are staggeringly unaware of these facts.

I keep telling these people to go to /r/linguistics instead, but thus far, nobody has taken my advice. Which is a pity, because I do give excellent advice, especially in this case.

But seriously - nobody knows how they talk. It's like trying to explain the biomechanics of walking. Sure, you've been doing it since you were a toddler (probably?), but that doesn't mean you have any understanding at all of what the hell you're doing as you propel yourself from place to place. I bet you can't even explain how you adjust for your varying center of balance!
