I'm not going to belabor this point to a newbie; but by way of example, since I espouse embedded-age creation, I'm a backwater Christian -- anything else, and I'm either brainwashed or a freak in a freak show.
Ah, I see. My status as a 'newbie' is important somehow, though you haven't really explained how.
Besides that, I see a false dichotomy, also known as "the fallacy of the excluded middle". You present a series of options and assert that your list is complete.
You also don't attribute the statements to any person or group more specific than 'my cohorts', which could be quite a few things, but from context seems to be people who accept science and post on this board. Thus you make sweeping statements about a group of people you don't identify clearly and don't know that well, which are thus difficult to prove, and then provide no evidence for them.
You found "in a freak show" as a third option to "brainwashed" and "backwater", but there are still more options, and some of them don't have connotations you'd find negative. I'm still interested to see if you can find them.
Finally, you will find, if you look through my post history, that I have in fact called out "evolutionists", atheists, and other people I agree with for weak and/or fallacious thinking. I don't find it quite as often there as with creationists, but it is still common. (you'll also find some moments of weakness where I don't live up to my own standards, but I'll own up to that. I've been better as time goes on. )
