No, I don't think it's "rather rude" to respond in such a manner to the suggestion that drinking beer, or any other alcohol, while flying is ok. You already knew it was a bad idea, hence your derogatory comments "getting their panties in a bunch" and "untangle your panties".

While it's obvious you have no regard for this important safety issue, or you're just trolling for an argument, this is a beginners forum. It does not seem appropriate to advocate ignoring established safety rules, or belittling those who do stress safety.

Do everyone else around you a favor and leave the beer at home, you will survive without it.
