Why do people have to be so rude to me instead of helping me to straighten out misunderstandings on SW?

Rude and hateful people are the bane of social media. They take advantage of their anonymity to act in ways they never would in real life. All we can do is block people like this and report them, when appropriate. The good news is that most people don't act like jerks, either in the virtual world or the real world.

Sorry you're having this problem. Just know that you are far from alone.
