Good observation.
The march "organizers" who asked participants to wear white t-shirts claimed that white symbolizes "peace."
Mmmm-hmmmm....
But, as you recall, a purely plain white t-shirt is also a garment of Latino gang-bangers, and in the old days that -- along with perfectly pressed khakis and a Pendleton shirt -- was the uniform.
This is no "symbol of peace." Another LIE.
