FrumTeens: Ramban is Apikorsus!

Here's where the FrumTeens Moderator clarifies his definition of apikorsus, which elsewhere on his website is extraordinarily sweeping, but here is merely very sweeping:

Any pshat you say that you honestly and objectively, without any outside influences or negiyos, derived lishmah from the torah, is, at worst a mistake.
But an idea that you had preconceived, or that you decided based not on torah bu on science or psychology or sme other outside influence, or your own negiyus, or whatever, if that idea is contrary ot the torah, and you try to fit in your outside-the-torah pshat into the torah, you are in essence twisting the otrahs words, NOT deriving things form them; you are trying to make the torah agree with you, NOT you agreeing to the Torah. And so if yuor pshat is correct, youre OK. But if its against the torah, youre not a toeah but a megaleh panim batorah shelo kehalachah. And that is apikorsus.

Well, there goes the Ramban - see his Peirush on Vayikra Perek 12 Possuk 2, where he says that according to Greek philosophy, Chazal's explanation of a possuk is not correct (he notes that the Greek view is also supported by Onkelos, but it's clear that this is only being brought for supplementary support). Ramban might also have been caught out on apikorsus for what he says on Breishis 9 possuk 12, but the Greeks happened to be correct on that one. Lucky break for Ramban there!

Of course, we must ask, what does "contrary to the torah" and "against the torah" mean? According to who? Frumteens doesn't say. Based on his other posts, the answer is probably either the Satmar Rav or the FrumTeens moderator.
