Opening fire on a group of children… The person with a mindset that justifies an act of terrorism and cowardice like this has given up the right to be treated as human.
That politics or religion can be used as an excuse for this act should make us seriously reconsider both politics and religion.

As you indicate by your comment, the alleged perp is identified as a far-right, Christian conservative. What is it about religion here, and there, which drives these folks into the land of bat-shit crazy! Same for hard-liners in the Muslim faith, Judaism, etc. Religion seems to bring the worst out of humans.
So true and so sad.
