Is Greer real?

After the recent whistleblowers all claiming Greer is the real deal I am left a bit confused.

I used to be pro-Greer.

Lately whenever I’d seen him speaking he seemed very snake oil salesman. It made me uncomfortable believing what he was saying.

But with Jake coming forward - I wonder if I’ve just read the room wrong?

What is the best evidence either way about if he’s the real deal or not?
