They were dressed in beige clothing with excerpts of poems on them. The problem is it doesn't seem to have occurred to the designer that from a distance, and when people are bent over a handle pushing a float, no one sees the writing on the clothes. And normally one wants attention on the float, not the pushers...

Apparently there was also a float with black people on it representing the new diversity, etc., that happened to be pushed by white students, but either no one bothered to have a photo of that one, or it didn't get online and go viral.

The one that did was the first of the parade, first reactions went viral, and after that, no one wants to stop and think any further. When the point is to display one's superior sense of moral superiority and one's politics, facts just get in the way and no one wants to know them....

The organisers were "guilty" of not thinking of organizing the float pushing students by race to ensure the "optics" were politically correct.
