I don't see the point in trying to convert BMC drinkers to craft drinkers if they don't want to be converted. If your friends like what they drink than that's what they should drink. I'd just tell them to order PBR or Stroh's if they want to drink something that they know they will enjoy. On the other hand, if they want to try something different by all means start proselytizing. Just make sure you ease them into it with something subtle and not overly hoppy, maybe the Reissdorf Kölsch.
