From my perspective, I didn't really see it that way. Like any country, the history curriculum focuses on China's history, focusing primarily on ancient history (pre-Qing dynasty) for 3 semesters with one semester of modern Chinese history (Qing to present). While there certainly was a nationalistic tendency in many topics I would regard the information as historically accurate (as compared to courses about east Asian history here in the US). And in reality, my many friends in China with whom I've maintained contact over the years do not have this sort of mentality and are against censorship and much of the nationalistic messaging.
Another interesting note that people here have no knowledge of is professors in China are often times anti-CCP. Many professors take this to the extreme and in papers will often just give a bad grade if it mentions any good policy by the CCP.
On a semi-related note, the comments many make here on HN about China make me extremely uncomfortable. Not because they touch on sensitive topics but because they smear an entire population of people as liars, thieves, and mindless followers. Replace the word "China" and "Chinese" with "Italy" and "Italian" in many comments and they could have been written back in the Ellis Island days.
