Mr Fogg, there are opinions and there are facts.If you post the former as if they were the latter, your credibility suffers.

Many countries have legislation forbidding the consumption of pax brought alcohol. A few examples:

Canadian Aviation Regulation (CAR) 602.04(2)(a) states in part..."No person shall consume on board an aircraft an intoxicating liquor unless the intoxicating liquor (a) has been served to that person by the operator of the aircraft..."

Australian Government Civil Aviation Authority: The only alcohol you may consume on board an aircraft is that which is provided by the cabin crew. You are not permitted to consume your own alcohol once you have boarded the aircraft.

Where there is no national law, or in addition to the national law, many airlines have the same rule in their conditions of carriage. As pointed out by Mr Scumbag.
(Conditions of Carriage: a civil agreement that govern the relationship between you as a Passenger and the Carrier regarding passenger carriage on an aircraft pursuant to a ticket on which an Airline Designator Code appears for that flight or flight segment. Passenger rights and duties towards the airline and vice versa in this matter are outlined in the Conditions of Carriage. We advise passengers to read the Conditions of Carriage carefully)

You buy a ticket and thereby agree to abide by the conditions of carriage.
You are automatically subject to the law governing air transport.
You then board an aircraft and proceed to drink your own beer.
The initial fault is yours Mr Fogg.
You behaved in a manner (by drinking your own) that has caused most FAs endless amounts of grief in the course of their career, and in a manner which is both against the law and against the conditions of carriage.
You then accuse the FAs of having an attitude problem.

YOU Mr Fogg put yourself in a position where you break the law and are rightly considered by most FAs as a direct threat to the orderly and safe execution of the flight.

No amount of obfuscation will change that.
