For champions of "diversity" especially.
They just don't see how their agenda tramples on others, diminishing diversity, when they don't agree with their way of seeing things.
It's scary when you realize that homogenous thought control is the tool of dictators. Free press and respect for open discourse; these are the hallmarks of a democracy. So these spoiled kids try to censure opinions but end up showing disrepect for a US Senator.
Another irony is that this would happen to McCain. He prides himself as being the darling of middle ground. Now he finds himself being hated by BOTH sides, the conservatives and the libs. It has to be confusing to him.
I remember a political ditty from more than twenty years ago that McCain can take comfort in.
"Hello, my name is Johnathan White,
I'm hated by the left. I'm hated by the right.
So I must be doing something right."
