All the points here have a certain validity. And taken as a whole, they show a real wishy-washy entity. This doesn't match the portrayal of "the same today, tomorrow, yesterday" that most would have you hold.
A self-consistency is decidedly missing. It's very much like the insane relative in the basement or attic that no one will talk about.
Overall, bottom-line: something is very fishy!!!!
