Bad behavior tolerated? - Shakespeare would disagree

Why is it that rude and blunt people, albeit honest, are often tolerated and even commended in society?

Example

Person A puts up a status on facebook that insults less physically attractive people.

The public response as follows: 20 likes. 17 comments of praise.

I was shocked! I knew a good handful of the people who liked it in which all of whom I knew to be quite friendly, so why were they promoting such bad behavior?

Then it hit me; people weren't liking it because of what Person A said, they were liking it because they all wanted to be on his good side.

I know some might argue that he was just being honest, but before you respond, I'd like to point out that being blunt is not the same as being straightforward. When you're being straightforward, you're also being respectful. On the contrary, to be blunt really, is to be rude.

Shakespeare - Taming of the shrew

In Taming of the Shrew, Katherine is portrayed as the "bitch". Nobody in town likes her because of her rude personality. In fact, almost all the townsfolk put her down. When Petruchio, an understanding gentleman asks her to calm down, she goes on to declare that she will not, and that she will continue to speak what she feels or her "heart will burst". She grows furious, telling Petruchio that if he doesn't want to hear it, then he shouldn't listen.

There is a common phrase in our time that goes like this:

"If you don't like it, then don't listen."

You have probably heard that phrase before, but to speak with your emotions in place of your logical reasoning is to be irrational and so displays a lack of self-control.
Shakespeare, in the Taming of the Shrew, demonstrates with Katherine, that by having your emotions overcome your logic, you could only embarrass yourself. So perhaps next time you feel like blow a fuse, think twice before you act negatively on it.
