I think those of us who have, or hope we have empathy, are taken aback by those who find it weak or deny its very existence becoming apoplectic when none is expressed over the guy who disparaged the very concept. Charlie Kirk, for those who read the bible, "sowed the wind and reaped the whirlwind".
Charlie Kirk was the first one to tell you that "some deaths must be overlooked" to further the Second Amendment absolutism he believed in. He never seemed to think he might pay the price he was so easily asking school children to pay?
Blowback happened for Charlie Kirk. Do I like my fellow Americans being shot down in broad daylight? NO! But, no one should ever ask of others what they are not willing to pay themselves. I do not wish to pay this price, therefore I would place MANY restrictions on gun ownership.
So many times it seems that those who advocate for policies that do obvious harm to innocent Americans, and are easily proven wrong-headed by comparison to other countries with different policies, never pay a personal price for the harm they are ok with happening to others. The irony is too delicious for some to resist.
