Indeed they OCT does cover more, and that doesn't mean that it isn't or shouldn't be subject to intelligent criticisms.
What isn't intelligent, are various critiques offered by the likes of Krupp who, fortunately for the rest of us, often raise points that laymen can easily decipher, which in turn demonstrate that their degrees, which they flaunt, always, don't make any difference. I've seen this time and time again, and while I favour the ideas-as does Jason Colavito, a seemingly competent skeptic - I also wonder if these pseudo skeptics actually lack a truthiness gene, seriously...
You might too, if you examined how stupid their points can be, and how they seek to defend these ideas once their flaws are brought to light. Normal, healthy people don't do that. Maybe that's what drives them, a dim awareness of a pathology that they can't purge.
Let me find another link by another well known pseudo skeptic, and I'll show you what I mean.
