I am not saying that racist views are acceptable. I am saying that racist views only matter if the racist is in power. You can't be racist in any meaningful way, such that your racism affects large parts of society, unless you are in power. That's all. Who cares about a powerless person's racist views? They are of no consequence. There is no redefinition of the term 'racism' involved. What does matter is if the congress, the police, the judges, etc are all white and consistently act on racist views.
