I wonder what percentage of total graduates walked out? The video shows maybe around 50 people at all. The title makes it seem like everyone graduating walked out.
It might seem like a broad opinion, but that’s the reader’s own opinion either being reinforced or rejected by a single line of text.
The reader may wish the disagreement wasn’t documented at all, because it doesn’t meet their own personal editorial standards, and they like telling someone they don’t pay how to do their jobs.
But factually, there’s nothing incorrect about what was observed and reported.
