Oh dear, this is how wars start :-) I'm sure Gunradd wasn't making any "threats" He mentioned "adverse results" I assume to mean you could well receive a swift kick in the pants or maybe a good telling off for dictating what people should and shouldn't do. I certainly never saw any threats in his post. Perhaps you are too worked up about others thinking differently to yourself. Try reading what people write, not what you read between the lines. I'm sure he was simply giving you good advice. Take it that way and there's no reason for anyone to get upset.
Sheesh, all this over a tiny box in a plane. It's not worth the grief.
