VIOLENCE. NO. JUST NO.
It is OK to have differences. It is not OK to shoot people, for any reason whatsoever. Practice kindness Practice peaceful discussions. Lock up, or get rid of, any guns you might have. Care about one another, one person at a time. Know where your kids are; know what they are doing; know what is in their room; spend time with them, listen to them. Smile at people and be polite; one interaction at a time! We can turn things around, but we have to believe we can, and try. Love your own children above all else, and let them know!
