This video is by Amir Odom. A gay black man. He directly counters all of what you're using as an excuse to justify murdering a man in public in front of his wife and children.
Also, the perpetrator was vocally NOT "on my side". He vocally hated everything Charlie Kirk said for a LONG time before doing this. His family didn't, but he did.
