Who has never been called names, experienced an insult or embarrassment or a threat?  The whole idea that we should attempt to convert the world to pacifism while we sit back and feel sorry for ourselves is the whole "snowflake" mentality that has turned our nation into a land of victims.  What a pathetic group we've become when instead of teaching people to be stronger, we propose laws against hate speech, relying on the government to constantly protect us.

"Turn the other cheek" is surely a metaphor for not retaliating, as opposed to not defending oneself against a violent attack.  So, we don't call someone names in return for being called a name.  Rather, we say, "Sticks and stones....," and become stronger as a result.
