Reading greggarious' first comment, the reader might think it was meant as a joke or extreme reaction posted for 'affect'. Reading the continuing comments by gregarrious, it becomes clear that he actually thinks this is a reasonable response to someone entering his room. In some states as indicated, 'stand your ground' type laws give him the basis to believe this is reasonable.

In most first world countries that consider themselves 'civilized' gregarrious, this kind of response is not considered reasonable at all.
