Rarely do I read remarks so condescending, callous and cruel. Even instrumentalizing the tragic deaths of Shepard and Floyd to dismiss the hurt of another person on its own is absolutely sickening.
I'd like to think that this cruelty is backed up by a good motivation. Maybe the author hurt you or someone you know. Maybe you sympathize greatly with the victims and you're motivated by righteous indignation. But no matter what, I'd really ask you to reflect on whether this kind of unempathetic approach makes the world better or worse. Because this is exactly the sort of incredibly tasteless comment a bully would write.
