Joe Biden was asked to leave very publicly and the store screamed it from the rooftops and became heroes.
Red Hen quietly and privately asked Sanders to leave. She made it public.
For DECADES the political right has considered it a point to be as rude, crude, vicious, vulgar, and insulting as they could. They called it being "politically incorrect". And courtesy had become "political correctness", a thing to be avoided. No one was exempt; sick children, dead children, parents of dead children, disabled veterans. Then they united (with Putin and the oddities of electoral college) to put into the highest office a man who in the very first debate said the biggest problem facing the country is "political correctness" and went out of his way to show he is more rude, crude, vicious, vulgar and insulting than anyone else. No one was exempt.
