Offense as Control

I always thought if you let people offend you, you let others have control over you. I still believe that is true.

But what I see now, is people feigning offense in order for THEM to have control over others. They pretend there is a Freedom From Offense in the Constitution, offend everyone around them on purpose, and then feign offense if someone stands up for their rights and beliefs.

I find most people who are offended are thin skinned and/or realize they are really in the wrong. The offense is a defense mechanism.

Why would anyone let someone else get away with this?
