It's called a starting point or speaking point. One shouldn't always spew their beliefs in an instant if they are truly engaged in meaningful conversation.
I asked the question because pro-gun posters are being heckled with labels such as paranoid and afraid of their neighbors.
Having a military is admitting the same, imo, albeit on a much larger scale.
Let me get on a personal level, Jake. I never owned a gun, ever, until about the time I had my third child. My wife was jogging on our street and a guy pulled up and grabbed her trying to force her into his vehicle. Luckily, my wife is kind of a badass so it didn't work. Not more than 3 months later we had someone break our backdoor while we were asleep and entered our home. Thankfully, he had broken into several homes that night and police were on his trail. Almost the same time he entered police came right behind him. He had held another family that night at gunpoint.
I decided to buy protection as a DUTY to my family. I don't expect everyone to agree with me, but I would expect most reasonable people to appreciate my right to do so.
