Yes, a dumbass staff member (who lists classes online, not a professor) goofed when he/she did not explain that this statement does not exclude other people:

This class is for people who identify as Black, Indigenous, Latinx, Asian, or other people of color.

And soom fixed it to say:

This class is designed to enable Black, Indigenous, Latinx, Asian, or other people of color underrepresented in the sport of rock climbing to learn the sport and to feel included and supported. The class is open to all Cornell students interested in learning rock climbing with this special focus.

The course could not have been "racially-segregated" per Cornell rules, and did not note that non-BIPOC people were excluded, and no one "frantically scrubs website"

That's not how university administration works.

The assholes at that website allow for this freshman student to post clickbait that's easily debunked.

What happened is that an idiotic staff member failed to list the course correctly, and then corrected it.
