It is a commercial. Don’t expect The Communist Manifesto 2.0. And the message is: “relax, have a beer and talk about your different points of view with people who are DIFFERENT from you.” As such, it’s way better than commercials whose message is: “drink our beer and you’ll become a babe magnet!”
Of course, if you are just so radical that you are unable to sit down and discuss anything with people who have a different point of view, then you won’t like it.
I suggest you take their advice: have a drink and a talk with people who are different, see what you can learn from each other.
Life is not a contest with either two options: winning or losing, beating the other guys or being beaten by them. There are more nuances to life.
You don’t even have to drink beer.
And when you drive, never drink! 😉
