Ok. Then my answer to that is roughly this:

I'll admit it's rather shaky and I'd be saying the same thing if I'd merely been brainwashed. It doesn't feel like it was precipitated by anything other than legitimate moral argument, though. If I can be brainwashed out of my "terminal values" so easily, and it really doesn't feel like something to resist, then I'd like a sturdier basis on which to base my moral reasoning.

This could of course use more detail, unless you understand what I'm getting at.
