The "message" is that the phrase is drawing more people in than pushing people away. The vast majority of the audience likes it, it's become a staple on a lot of bowling leagues, etc.
I realize not everyone likes it but don't kid yourself; it's got buzz. I can understand that you personally might not like it but I can't understand why you feel that "he appears to be getting the message loud and clear." The anti-Hambone group isn't winning this debate.
