You're arguing with an oversimplified model of the complaint about Weinstein. It's not that Weinstein has a theory that's orthogonal to mainstream physics, but rather the means with which he pursues the inquiry. He doesn't write real papers, when he released the GU paper he copyrighted it and claimed it as a "work of entertainment", in effect demanding that the rest of the field not cite and address it. That's not how papers work.

The problem, as I understand it, is that Weinstein simply isn't "doing science". He's "doing big thinkies" and then complaining when the world doesn't snap to attention. That problem has not much at all to do with his specific ideas.
