It doesn't. It's just a reply to someone who doesn't agree with the lifestyle. It's a typical response when the rhetoric well has run completely dry hoping others will agree or laugh. Kind of like canned laughter in old 70's TV sitcoms to make the home viewer believe the audience is captivated and laughing at the skit at hand.
No biggie, I accept the fact that it's out there, but I don't have to agree with it.
