So, to rephrase, most of your classmates had a grossly distorted view of the importance of minor academic setbacks as well as a ridiculous sense of entitlement, which supports what the article was saying.
Were people being entitled? Yes, definitely, almost everyone I knew felt entitled to a C- or above just for showing up to class every day, turning in the work, and paying the exorbitant tuition fees in the first place. But a poor grade was a multiple thousand dollar loss at best to people widely incapable of making more than minimum wage. I think the general emotional response is warranted in a lot of cases.
(Your characterization seems odd to me anyway. I don't see where the person I was responding to made an assertion that something is so I don't know how you could read my response as being "no, it's not"; he simply provided an anecdote of his peers' mindset and I rephrased it.)
