Dear well-intentioned people on the Internet thinking of doing something nasty and destructive out of a misplaced sense of self-righteousness,
I am not comfortable with you tracking down people who write offensive and nasty things on Facebook and contacting their employers.
You are not the Internet police. You are not 4chan. It is beneath you, and it changes no minds. It marginalises rather than educates. It’s indistinguishable from bullying.
Would you like everything you’ve written on a computer to be sent to your employer? Or certain edited highlights? No?
Then don’t do it to others, no matter how horrible they might be. You’re better than that.
