You bring up a really good point and it made me remember something.
When AJ is with Blanca, Blanca being that latino chick, that's perfectly fine, good for AJ.
But when Meadow sees that black dude in college, Tony is instantly confrontational.
Meadow must've been mindfucked when her parents were right about that black dude not being a good boyfriend, but they were right for the wrong reasons. Tony's angle was that he was black, forgot Carmella's spin. Tony was against him due to race, while the black dude was against Meadow due to class and how her family is below his.
