"Awareness Reduces Racial Bias"

No, I'm not saying heightism has the history of racism. For some reason I always have to add this disclaimer.

The main point is here:
"After being made aware of their racial biases in referee calls through widespread media exposure, individual National Basketball Association referees became unbiased, suggesting that raising awareness of even subtle forms of racism can bring about meaningful change."
Many people advocate shutting our mouths instead of raising awareness about height discrimination. That is not the way to go. The main difference is that people these days are taught racism is wrong, so they more willingly absorb the awareness. When it comes to height prejudice, they must also be taught that it's hurtful and not productive for society.
