No, if I were to be holier-than-thou I wouldn't be working toward the abolition of copyright (see comments from waaaaaaaay long ago, but they still hold. Copyright needs to go.)
I'm also not saying it's not hypocritical. Of course it's hypocritical. On the other hand, there's a difference between, and let's roll with your example here, the politician shagging a mistress once, getting caught, admitting it to their constituents, typically going into family counselling and all that.. and the politician calling for a press conference, saying "yeah, I shagged my mistress so what? Hell, she's giving me a bj right now" (cue camera pan to reveal mistress on knees behind the mike stand).. and not just once, but continually.
It doesn't make the singular infringement less bad, and certainly does little to repair damages done to their credibility as a champion for family values - but the latter scenario should have even the most devout of campaigners thinking he should pack up.
As for the straw man that you allege is just mine: I assure you, it's not, it's called sarcasm. Tell me you've never seen the comments that make that jump in logic ( unless those were all mine, too, of course ;) )
