Under these circumstances would you, with no prompting from your audience, consider it "professional" to start talking about your interest in strip clubs?

It would be no more or less professional than mentioning playing in a death metal band on weekends or being a volunteer at an atheist outreach group or helping organize protests to support gay rights.

Any reticence would be based on how professional I thought the others were, and if I thought I would be at a disadvantage because of narrow-minded prejudice about things that have no bearing on my work.
