This is the argument for deconstruction. And it has some points. But this argument has been used to discard traditions willy-nilly and that's a dangerous thing to do. You need to *know*, not just theorize, the reason for a tradition you wish to displace, because human societies have competed with each other for thousands of years (if not tens or hundreds of thousands), and those societies with traditions that worked better for them for whatever reason were selected for. Holding traditions as sacrosanct is a strict conservative position, and societies do have to adapt to new conditions, so being strictly conservative isn't the best position, at least in my humble opinion. But I can respect them.
