I found out this wild thing where the rightwingers for years have claimed every mass shooting is done by someone transgender. I assume most knew about it —but of course it has been debunked by many. Now the far right are running the FBI. We might need to consider future information in that light.
I have no idea about this shooting and it doesn’t matter for anything about mass shootings. We know they have become a cultural practice highly enabled by the ease of acquiring tools for the act. What motivates the right to home in on identity is their ideology motivates shooters much more often.
