I think you are confusing the issues!

You are confusing CRT (a system of analyzing society) with "sensitivity training." The two are NOT the same thing. Some trainers may use CRT as the basis for developing a training but poor training does NOT invalidate Critical Race Theory.

Per Wikipedia (as a quick source) regarding CRT

"Critical race theory (CRT)[1] is a theoretical framework in the social sciences that examines society and culture as they relate to categorizations of race, law, and power.[2][3] Developed out of postmodern philosophy, it is based on critical theory, a social philosophy that argues that social problems are influenced and created more by societal structures and cultural assumptions than by individual and psychological factors. It began as a theoretical movement within American law schools in the mid- to late 1980s as a reworking of critical legal studies on race issues,[4][5] and is loosely unified by two common themes. Firstly, CRT proposes that white supremacy and racial power are maintained over time, and in particular, that the law may play a role in this process. Secondly, CRT work has investigated the possibility of transforming the relationship between law and racial power, as well as pursuing a project of achieving racial emancipation and anti-subordination more broad"

This is a completely VALID means of evaluating society and has it's analysis rooted in facts on the ground.

I would also point you to the link here where a young woman puts her view of CRT.
