I don't see the issue with people not showing the "appropriate" amount of sympathy for Charlie Kirk. I tuned in and listened to him pretty regularly and I can say for a fact he was an extremely divisive and controversial figure.
Of course nobody should be murdered for their opinions but Kirk constantly fanned the flames of bigotted, mysogynistic, non inclusive and homophobic hatred and intolerence that often leads to political violence against marginalized groups.
His words were not the least bit Christ-like (aka Christian). In fact the things he publicly advocated for were pretty much anti-Christian.
One could argue that based upon his words and actions the only thing "Christian" about Charlie Kirk was his claim to the title.
The Bible says you can judge (identify) a tree by the fruit it bears. Charlie Kirk sowed hatred, division, paranoia, and intolerance. Contrary to the apparent beliefs of many on this board these things are NOT Christian values.
So no, although it is sad that such an ignorant, tiny-minded man should have his life snuffed out so young leaving his little babies fatherless, you can't blame people for not being excessively torn up over the loss of him.
Some may even consider it poetic justice.
When you dedicate your life to preaching hatred hatred has a way of finding it's way back to you.
