The problem are those that think of their guns as their friends or as their children.

school shooter of Oregon out of the news. Bill Mahar showed his photo. He was a white male christian that left a manifest and claimed to be a republican and lived with his parents. We all know had he been Muslim or Black, his picture would have been seared in our collective memory.
These young white men should have to prove that they need a gun to hunt for food or part of a State sanction Army as the second amendment says.

Um...the shooter in Roseburg was mixed race. His mother, Laurel Harper, is definitely African-American...

and his picture wasn't seared into our memories.

You were basing your point on him being white...which he wasn't.

As for proof, a simple search on "Chris Harper-Mercer mixed race" returns countless links. Here's a screencap of his profile on a dating site, in which he self-identifies as "mixed race."

Haven't most mass shootings the last few years been perpetrated by young white men?

I think your premise is skewed.

They cover the ethnic gamut with white being the most common.

As Bill Maher stated, these guys aren't getting laid. They don't even have any female relationships because girls find them creepy.

This is our early warning "Minority Report" system.

Perhaps legalized safe prostitution would help?

there was a school shooting in Minnesota and Oregon who were Native Americans, the Ft. Hood shooter was Aribic, the navy yard shooter was AA. I don't think race is the primary cause and it is a mistake to focus on that.
