I agree - from afar there seems to be a very unique culture of fear and urge to "protect" prevalent in the US.

I was reading a reddit discussion some time ago, where most commenters concluded that it's fine to shoot a burglar entering your house at night, which feels very alien to me. Sure, it's a frightening situation, but in my mind a burglary clearly doesn't justify the, potentially deadly, use of a gun. Those are not equal actions and measures.
