You think hes wearing a gun at work in a grocery store checkstand because someone saw a cougar at a far off trailhead? A cougar that ran away as soon as it saw people?
Bullshit. Hes wearing a gun because he has on a KKK shirt in public. Hes using the gun to defend his racism, full stop. Hes saying quite clearly that if you confront him about his racism, he may kill you.
Stop giving racists even a shred of plausible deniability, even when it is as thin as the above.
