Maybe I’m the dumb one for not understanding what this lecture was supposed to be about. The description on the University of Texas at Austin’s website says:
In the wake of renewed attacks on Muslim and Muslim-adjacent communities, the hijab and turban continue to be enveloped as important material objects in the racialization of Muslim and Sikh bodies.
Okay, so far I think I understand. The sight of turbans and hijabs triggers racists (religionists?).
