Respect goes deeper than simply telling your children what they want to hear all the time. He may not like his parents at the moment, everybody goes through phases like that, but I'm sure that they think this is ultimately for the best. I agree there may have been a lighter way to put it though.
I'm only going off what I've been told, I have no idea what his situation is really like. To me it sounds like this has been an on-going thing, you have to be able to change yourself before you can try to change things around you. Being treated like a failure is certainly never a good thing in any aspect, but being told these things can force you to face up to your problems, be it school or whatever, and work towards fixing them.
Regardless, I'm not going to continue to argue a point when none of us have any information; it's really not fair to Aurora. If he made this thread looking for help I'm sure the people here will try to give him some good advice providing he gives some details about his situation, but at the moment it just looks like he's using it to vent his frustration and get sympathy. Nothing wrong with that either if he's angry.
