Is it some logical argument she is unable to find a fault in? If so, then how come there are multiple schools of philosophy disagreeing on the basics?
Maybe their level of logic is just low, or they have bad thought habits in applying that logic. Or maybe there's some system level reward for not agreeing (I imagine that publish||die might have such an effect.)
I don't see why you'd think it faulty to mention the possibilities there - remember I'm not claiming that they're true, just that they might be potential explanations for the suggested observation.
If you want to share the reason for the downvote, I promise not to dispute it so you don't have to worry about it turning into a time sink and to give positive karma.
Sam Harris is here offering a substantial amount of money to anyone who can show a flaw in the philosophy of 'The Moral Landscape' in 1000 word or less, or at least the best attempt.
http://www.samharris.org/blog/item/the-moral-landscape-challenge1
Up to $20,000 is on offer, although that's only if you change his mind. Whilst we know that this is very difficult, note how few people offer large sums of money for the privelage of being disproven.
In case anyone does win, I will remind you that this site is created and maintained by people who work at MIRI and CFAR, which rely on outside donations, and with whom I am not affiliated.
Note: Is this misplaced in Discussion? I imagine that it could be easily overlooked in an open thread by the sorts of people who would be able to use this information well?
