It's about consistency. This is man who said, in the wake of school shootings, that a few gun deaths every year is a worthy cost for gun rights. This is a man that said empathy was a made up woke term that causes a lot of damage.
Why should anyone have empathy for him being shot at a school? Not caring about those kinds of victims was his entire platform. This is karma, divine poetic justice, and I'm not going to ignore that. He got precisely what he deserved.
