Yes, totally agree with you on everything! Here is Sam, fresh from being possessed by two different entities and he has to listen to Dean's "woe is me" speech instead of being able to express how he feels. No wonder the poor boy feels so defeated. With the way this fandom works, the longer the separation lasts, the more hate Sam is going to get I'm afraid, because we still won't get his point of view and so many feel he should grateful instead of angry.
