You were obviously drunk leaving a pointless reply as such.
Tom2050, since you have some difficulty understanding that previous post, let me try and explain. Beer contains alcohol, which is a depressant, and is often associated with a relaxes social setting.
Have a beer would therefore translate to requesting one to relax. Or in other words not to care so much about a statement made by one person, or several people. Yes, some people don't like America. Some people don't like me. But I'm not offended when a friend makes a joke at my cost. Which is all that statement was.
