As far as what little I have seen about this, i will give the protesting students some credit and say that they didn't seem to disrupt to proceedings other than just getting up and leaving.
I can say I bet there were a few pissed off parents there. i mean....I have no idea what a year (or 4) costs at ND but if i busted my hump to get my kid through there....he/she damn will better sit through graduation. His speech was what??? 15 or 20 minutes??? You'll live.......
