The fundamental question here is - might there wisdom in what we have inherited that may be obscured in the myopia of the ideology and politics of the present moment? The fact that the reasons for something may not be obvious or can be reduced to a simple legal formula does not mean it arises from ignorance or animous. I see no reason to assume guilt of bigotry until proven innocence when it comes to those who have created and attempted to preserve an valuable institution, even if we come to the conclusion that a transformation of it may be necessary.
Here's the thing: if you think there is some fundamental wisdom in the state of affairs we inherited, you should be able to actually articulate that wisdom, right? But you haven't. Not only haven't you articulated it, you haven't even come close! Even if it's complicated, or non-intuitive, it would be instructive to hear your interpretation of the "wisdom in what we have inherited". But you've refused to give it, which makes it seem as though you're really trying to muddy the waters more than anything.
