Well, if you want me to state the obvious I could do that for you.  Yes, racism and discrimination are bad and the guy who told her to go back to where she came from is clearly ignorant.  Racism exists within every ethnic/racial group.  I am a visible minority and I found her use of the word "Aryan" racist in itself because it both, disqualifies the vast majority of whites who are not racist and ignores the fact that racism is dished out by people from every ethnic/racial /religious group in the same proportion as whites.   I used to work in an organization that employed a lot of Muslims and once when I suggested at a staff meeting that we make our reception space LGTBQ friendly by posting a small rainbow triangle to make our LGTBQ clients feel welcome, my Muslims colleagues opposed my suggestion and I was virtually silenced.  I am not saying don't criticize racism but simply that we should all fight it without making it look as if this is a problem that only affects one ethnic group.
