You might want to google automatic weapon laws for texas or just wiki it to see all the states, you can own automatic weapons in texas last I checked and in another state you can carry one around safety off no case.
Yes, I know the quote. However, sarcasm doesn't translate well in text and your "joke" sounded more like you were just being rude and then trying to defuse it by joking afterwards. My apologies if I misread your intent.
I also don't defend "my friends". I simply try to school people in internet etiquette so that Spill doesn't end up like AICN or IGN or the million other sites where their comment sections and trackbacks are just one long stream of angry trolls.
I would suggest possibly examining how you word things or consider adding something to the end of your sarcastic posts to indicate that you're joking around. Otherwise, things like this happen where someone thinks you're being serious and confronts you. Thank you for understanding and contacting me to clarify your position.
