That feeling you talk about in your last sentence is one that's familiar to me as well, because I get it all the time when reading SSC, and we've got to be suspicious of it- that's exactly how people who read <religious literature, cult creeds, academic papers> that confirms their preexisting ideas feel.
Not every thing you read is meant to change your mind. I had this feeling with SSC too (more frequently in the past, in the Meditations on Moloch era, less so now), but I can clearly tell that I had pieces of those ideas developed on my own, and an SSC article only let me put them in a refined form.
(Having been brought up in a pretty cultish religion, I'm now painfully aware of cultishness works.)
