Angry people aren’t great company. They can be grouchy, aggressive, and loud. Everyone is angry sometimes.
You may have noticed that the word “angry” is sometimes applied to people who haven’t actually displayed any of the above qualities. Even worse, some people are fond of calling entire groups of (other) people angry, or accusing just one person who belongs to an “angry” group of being angry, even if they’re not.
The idea is, if you don’t like the look of somebody or the sound of the things they profess to believe (or not believe), if that person says anything that challenges you in any way, she is basically screaming and punching holes in your walls for no reason.
Why would you listen to a person like that?
