One of the first things I did at Duck U law school was a 500 word essay on "justice".  

The main purpose was to teach us that "the law" and "justice" were seldom the same.  

One of the other things that was reinforced in law school is that  "the country was founded as a white racist nation."

If one reads the US Constitution as adopted, that is obvious. 

No slaves except the 3/5 counted for House of Representatives membership, no Indians, no women, property ownership for voting, 

That doesn't make one 'ignorant about justice'.   It just reinforces the understanding that for lawyers, 'justice' is seldom relevant to their job.

If you are charged with a crime, and are undeniably guilty, do you want an attorney who will seek 'justice' and thus make sure you are convicted; or do you want an attorney who will do his best to have you found not guilty so you don't have to go to jail?

"White male affirmative action" didn't help me pass the LSAT,  

Did you pass it?  Or even take it?
