This is a terrible story.
Because of social media, and because of the number of social media vigilantes who have nothing better to do with their life than harass people on line, on-line "bullying" is a thing. It's a stupid thing, but it's a thing.
Racist is apparently the worst thing in the entire world, bad enough to drive a civil servant to suicide.
There's something seriously wrong with people who are on-line social justice warriors on a full time basis. Crazy never sleeps. However, there is also something seriously wrong (or pre-existing) with someone who ends their own life because of something that someone says about them on line.
Fortunately, there is a solution to on-line "bullying".
Shut your f&cking computer and phone off and ignore all the morons.
