Tortured syntax and overblown use of terms are just part of the package with younger ex-mil guys, in my experience. It rarely has anything to do with whether they have good lessons to pass along or if they're good at teaching.
I find it's better to look past the superficial stuff and ask instead whether I can learn something from someone, and whether that's worth the price of admission. Haley and Defoor are both on my list of folks from whom I'd like to take at least one class, and I will openly share that I am setting aside some negative impressions of personal conduct with one of those two, because it has no impact on whether learning will occur.
If someone is a complete oxygen thief, or is great on some topics but out of their lane on others, I want to know that so I can spend my money effectively. Otherwise, I think it's a bit silly to insist on this zero-defect culture of video shoots where everyone uses polished, rehearsed lines and never ever forgets to show clear to the camera.
