That second-hand smoke is harmful to people's bodies is not a notion Outsider77, it is scientific fact. If you can smell it, you are inhaling the toxins from it. Your claim that the only racism that is significant is the kind that is a direct threat to non-white people's physical safety is bogus. Denying black people the right to sit on certain seats of the bus reserved for whites did not constitute direct physical harm and yet it was harmful. In effect, what you are saying is that segregation wouldn't be harmful to black people if they would just change their worldview (in their minds) to accept their second-class status in society. 
What is grotesque about your viewpoint is the degree to which it reveals your inability to empathize with the experiences of anyone who does not share your skin color.
