There is a difference (to me) of what constitutes an asshole. They are hateful pricks with no concern for others.

You dont need to be an asshole to fight one, you just need to be brave enough to fight one. Of course, they are assholes and they fight dirty, you will get dirty in the process.

First step, dont be a Asshole. After that dont support one. Then, dont raise any. Finally stand up to them.
