If you willingly make a douchebag "persona" for yourself, don't complain when people call you a douchebag.

I'd complain about people not understanding that a programmer with an electric guitar that shoots lightning surrounded by strippers might have been ironic.

Generally speaking, people don't like ironic douchebags any better than they like regular douchebags.

Really? Look at Sasha Baron Cohen. As Borat, he's an ironic anti-Semite. Most people have noticed this, and if they find him funny, like him. Those same people would not like regular anti-Semites.
