My guess is this paper read like it was written at the last minute, without much thought, and without much proofreading. Yeah, prof was annoyed to have been given that. It's not his duty to pat you on the head and pleasantly tell you that perhaps you should proofread what you write, and ask if maybe you didn't give him your best effort. He just gave you his unedited thoughts.

Thicken your skin and realize this prof just shoots from the hip with his comments. Complaining about the phrasing of the prof's comments isn't going to gain you much except further ire. If his complaints have merit, ignore how he phrases them and do better next time. And now you know that this guy seriously hates getting papers with obvious typos and structure errors--don't send him any more such work and you may avoid receiving further scathing commentary (and honestly, none of these comments sound all that bad to me.)
