i'm not perfect. just funny that now that it isn't obvious the shooter is a "left wing nutjob" and is a young white male again (surprise surprise) Marty now has had a chance to "chilled a bit and reflected more"

The correct response is to admonish the person who actually made the mistake here, which was marty jumping to conclusions and making a very widespread post as if what he was saying was fact.

Instead you admonish the person who points out the issue. Shrug
