Except that ya know, normally home invaders and squatters don't declare their intention to murder you and take your stuff before they move onto your property. This is nothing like squatters, or even people breaking in to steal your shit. This is people coming, by force, clearly stating what they're wanting to do, and putting your life at risk simply by being there.
EDIT: I just re-read the post you were replying to. I think their analogy here is very inaccurate. This isn't like a typical home invader situation at all, it's far worse.
