If I went onto social media after Hortman was shot and reviled her in some way then got fired for it, it would be my fault. If you go on social media somewhere where you are identifiable and promote violence and tell folks how much Charlie deserved it and get fired for it, it is your own danged fault.
If you wouldn't say it in mixed company in public, don't post it on Facebook with your image next to it. Someplace like this is much safer, but I still don't say stuff I wouldn't say in public here... Just no.
