Welcome to the forum. I left you a positive rep because I agree with your statement.
Since you are new here, I just wanted to urge some caution with regards to calling some people cold-blooded. I've found many ex-military to be far more comfortable with switching to violence then I would be. I think that goes with their experience in service when they've seen real combat in Iraq/Afghanistan. Some of them are the most caring people I know, and I would trust them with my life.
