Really, the title says it all. Do I need to elaborate?
Welcome to the internet, where other people seem to be just user names and avatars. There is a massive temptation to set aside the basic rules for civil discourse thanks to this cushion of anonymity. People call names, issue empty threats, and generally act like angry toddlers with a more comprehensive repertoire of vulgar language.
While there is a time and place for such language, this platform probably isn't it. As such, I have three simple suggestions:
Don't do that sort of thing. You're better than that.
Downvote those who do. That's one of the reasons the button is there.
Build a better vocabulary to express yourself more eloquently and thus raise the bar for public discourse.
As outdoors columnist Patrick F. McManus wrote, certain words are best reserved for when one is being charged by an angry rhinoceros, and use outside that context only creates confusion. Step away from the keyboard, read a good book, and relax instead when you feel the urge to vomit forth a juvenile stream of invective.
