We murder people with words even for small mis takes

 Why must we give people a verbal beat down online even for small transgressions? If someone misspeaks or days something unthinking, which let's face it, we all have done or will do at some point, people on social media have to go on angry attack. They pile on, get on the case to identify the person if the Internet doesn't know their name, give out their personal data, and pound them into submission. They want them to lose their reputations, jobs, homes, and even their lives in some cases,over things that in the overall scheme of things matter very little. What do we get out of doing that?
