Apparently the shooter was homosexual, and hated himself because of it.
So here’s a question: If he had accepted his homosexuality, would he still have done this?
We will never know, but if the answer is a reasonably possible “No” then what could society / government / law enforcement / etc. have done differently so that he accepted his homosexuality?
I don’t have answers but I do think it’s important to at least ask the right questions – and not to jump to conclusions about what the real problems are and how to fix them.
