And of course he's not above criticism. However, calling someone a "phony" means something to me. It means they act one way but are really another. They put on a front. Much if it can be seen in their demeanor but I'll give you, that's not it in total. Given that Hawking has ALS he can't really change his demeanor, it means you'd really have to prove your case to call him a "phony."
Granted, I'm guessing that this was the purpose of the thread, you wanting to lay out your thoughts on what makes him a "phony", so have at it, someone asked!
