Don't hold people up to unreasonable standards. People make mistakes. They say things they don't mean. They take things the wrong way. They say things they regret. They over-react to circumstances. etc etc etc. It's never going to stop.
Heck, some people have even flamed and insulted me because I've had the audacity to *gasp* defend someone who can't defend himself.
First off, yeah everyone makes mistakes, not too many compound them and then show little remorse.
Yeah Mike Brown will have trouble defending himself after such an act and then the following debacle.
Mike Brown has said many a time that he has messed up and the like. Difference is in those times he admitted it at the time and didn't wait for the backlash to mold his opinion. Damage is done.
