I'm not saying you're wrong, but there is a difference between constructive feedback and merely negative feedback. Most of what I've seen is feedback with little understanding of the situation or empathy, and I think that is why people have become negative about receiving any sort of criticism. I had a boss that was great at that, and I always got constructive feedback, but those managers are far and few between. Most of the time I get things like, "The project is late." without any understanding as to how or why this happened.

That's totally fair, and a great distinction. I will say that learning to ask for clarification on negative feedback is a good skill to have. Not easy when you depend on a job for income, for sure.
