1. A bias
2. People just venting and blaming it on S
3. People not fully understanding what S is and isn't and what S types are and are not like.
When people are biased or just venting it's usually obvious so I actually don't mind it as much (Not that I want to promote it!) as when people believe/spread incorrect information.
I'm really glad that Sarah cleared things up that seemed to be misunderstood.
