> When you're around other people, even ones who share your beliefs, and say 'I think we should murder that guy!' then in most crowds someone is going to say 'Hey fellow, are you okay?'

There are crowds where that guy is not there, is not heard, or doesn't speak up at all.

In those crowds, people reach out for their pitchforks and outright murder people.

If you take a frank look at history, you will notice those are all too frequent. Even in this century.
