What DO we give up to support racism? Plenty:

the minds of human beings

their contributions

Their friendship/love

Our unity of belonging to one species

Art and creativity/culture

Joy of collaboration

working toward democracy

the solutions to constant strife/ stress

violence, hatred, etc.

We give up our confidence of kicking that sick addiction you identified.

We give up the salvation of the world.

All of these cost everybody, no?.

What are the "benefits" of racism? unending pain.
