I thought you didn't know much about cte.
When trying to learn something about CTE it's best to ignore the CTE cultists - they know less about it than anybody. LowIQ here is one of the best examples of that - ask him anything about it and watch him tapdance all around your questions ("it'll all be explained in Stan Shuffett's 50th video, due out mumblemumble").You're absolutely right, he doesn't.
But he's been ignorantly pontificating about it for years.
CTE is a simple system made overly complicated to obscure the fact that it's pretty much like every other system. That dodge only seems to work on its "true believers".
Make your own judgment.
