Interesting.. but there's a few things going on here.
Most of those excuses he lists are real, pedos use them to rationalise what they are doing. I worked for QLD police and for a corporate investigations company in London who contracted to the Met. I have done plenty of CP investigations. Most Pedos have these types of excuses on their computers in amongst their sick pics and vids.
Either the author or Pedos (or most likely both) are tying pedos to Gays. "If they can have rights, why can't we. They're accepted, we can be too". I think this is pretty harmful/unjust to gays. You're either a pedo or not and the stats are the same for gay or straight. Yet some people still think gays are more likely to go after kids. They aren't. [edit: statistically the most dangerous group for your kids are catholic priests]
Gen Y's and subsequent gens are going to have a very different attitude to sex to anyone previous. They grow up with every type of hardcore porn a click away. It's gonna be no big deal for them. Where we used to talk about 69s (chuckle chuckle) they talk about triple-anal, dirty sanchez, space docking, etc.
Author is not impartial:
Exhibit A: Hardcore religious
www.hotels-gothenburg.net/de/christiannewstodaycom/There is no better recent illustration of the importance of this issue then the story of "American Worker" J. Matt Barber. His dismissal from the Allstate Insurance Company for his opposition to same-sex marriage and his stand for one-man, one-woman marriage is a true indicator of where America stands in the cultural war today.Exhibit B: Loony Right winger (Tea Party supporter)

So he has a wheelbarrow to push in this article, linking gays and pedos because it helps his anti-gay stance.
Lastly Dinsdale, what is "western culture as we know it"? I mean your culture is not my culture. Your kids culture is not your culture. Everything changes every day and everyone has a different perspective. Try to define aussie culture and all you get is 'fair dinkum' and meat pies. Pffft.
