There is a simple maxim that I use to express this situation, 'when tolerance becomes a one way street, it leads to cultural suicide. '
I think the most tortured place in hell should be reserved not for traitors, but. . . for cowards. The weakest, most spineless losers. Because it seems to me that traitors? At least they made a choice. But cowards? They just run around biting their fingernails, totally afraid to do anything. Which is totally worse.
