Even if he is mentally ill so he attached himself to any cause, it doesn’t mean it is NOT racism. Would it mean it is NOT murder because he did it while mentally ill? I don’t think so. Liberals might, but I don’t.
He probably is mentally ill. No one in their right mind would do and even think such evil things. But it is ALSO racism and also murder.
Murder is an act, racism is a POV. A totally deranged person has a totally deranged POV. It is absurd to assign rationality to an insane person.
