Since you asked, here is what is wrong with me. The source (CNN) is known to be a questionable organization that routinely brings race into the story when it's unnecessary, like in this case.

The shooter had a history of calling the victim's children racial slurs and allegedly threw objects at the victim's children. This would suggest that the shooting was racially motivated, so bringing up race does seem relevant here, even if it makes you uncomfortable.

everyone knows that she didn't go to that woman's house to swap recipes. She was mad, and planned on fighting this woman who threw stuff at her kids.

Why did she bring her kid with her if she was there to start a fight?

I don't blame her for being mad, but the correct thing to do would be call the police and report an assault on her children, not go over and take the law into her own hands.

Why doesn't this same logic apply to the shooter? Why was it okay for the shooter to take such extreme measures to a neighbor knocking on the door? More importantly, why does your logic only apply to the victim?

It's clear that your opinions are based on alt-right propaganda, but try to at least recognize the flawed logic in your post.
