PerlMonks is two things - a teaching community organized around perl and a social community. If you ever follow the chatterbox you'll see all manner of topics come up from religion, politics, sex, lots of puns, and of course perl. I don't think its unusual for a social network of people to bring up these topics - heck, some of us spend a lot of time here. Its only natural.

Heck, join in. Its great fun.
