I think there's a trap whenever you try and pursue an unbiased, universal perspective or theory or truth (and not just in this one space): it can be really easy to lose sight of your own biases and flaws, which always exist, and always impact your perspective. None of us can claim to be fully rational and removed, so whenever we try and venture into the realm of universal truth, we must always keep our own biases front and center and account for them as best we can. That isn't to say we shouldn't pursue those truths, but I think the point being made is that Rawl's framework encouraged people to sweep their own biases under a rug, which is a dangerous thing to do.
