Yes, leart ... apparently we are understanding and agreeing perfectly!
The only thing is when you talk about the Honor's courses ... while it's probably true that in the White high schools blacks may not be encouraged to take those courses, in the predominently Black one's (and yes, most schools out here are intentionally segregated ... they will build a new school in a Black neighborhood just to keep from having to bus them to a White school!) such honor's courses are offered and encouraged. And there's a fairly good number of students who take advantage of them!
It's a beautiful thing to see at graduation time!
