Clearly the only logical solution is to ban thumbs and index fingers at school. We won’t be able to control little kids from making gun gestures so let’s just make it to where they can’t make them anymore.
That will make us a much safer and peaceful country.
From Jane Fonda to Jack the Ripper, every successful criminal in history has had opposable thumbs.
Banning thumbs wouldn’t work with my kids, they know daddy has hammerless revolvers at home and would just be pointing at people then blowing the make believe smoke from the fingertip.
