Who gave him the title of "bitcoin evangelist"? He himself? This guy was shilling shitcoins, including bcash, like crazy, this alone is enough to disqualify anyone as bitcoin evangelist.
To be fair, "evangelist" shouldn't be a sort of authoritative title in the first place. Evangelist pretty much means someone sort of campaigning/advertising something(or "converting" people, when talking about religion), which he is, regardless if he is preaching Bitcoin in a good or bad way.
