I think the quibble is that it's being equated with homosexuality, as if both are simply contentious issues. Surely anyone can see the stupidity in 2013 of drawing parallels beyween homosexuality and paedophilia merely because both are seen as 'unnatural' and 'perverted' by some unenlightened minority? Even talking about the two in the same breath is offensive IMO and reeks of bigotry.
As for homosexuality 'stealing and programming children', well, there aren't enough eye-rolls in the world to respond adequately to that.
Also, although it could be argued that for some people it is natural to be attracted to pre-pubescent children because it is the way their brains are wired in the same way that gay people are attracted to their own sex because of the way their brains are wired, paedophilia is also about power over people rather than anything sexual in many cases - children are easy targets for people who need to have power off others.
Either way power or attraction it is still obviously 'wrong' - but should people who prey on children for those things be 'treated' in the same way?
