I need no studies. I grew up for many years, where I was completely almost the only one of my race with another race mainly and I know for a fact that everyone is racist. It is nonsense to claim otherwise. Just crazy what has happened, we've lost perspective via our own compassion and wanting to do 'right'. 
What is most telling in current discussion is how the words 'Racist' Racism' keep popping up without any mention of the words prejudice and discrimination, in particular the latter, which is all that matters.
You can cite the studies but the individuals coming forward with their censorious use of the word racism, do not ever show why their censorship will stop discrimination because...they want to discriminate against others.
