Oooh, I love picking shit like this apart piece by piece. I know it's a waste of screen real estate and database storage, but it's sooooo fun...
You've got a point there. If everyone were atheists I'd be willing to bet sex with any consulting child would be legal. Incest would be legal.
Possible, but highly unlikely. There are a few who feel that as long as everyone's consenting, it's fine, but for the most part it's considered a sign of poor socialization and/or severe emotional problems, thus putting it outside the realm of "consentable".
All drugs would be legalized.
Only libertarians and quacks want this. The rest of us feel that a regulatory framework is necessary to keep the bad ones out of circulation. Opinion on less harmful recreational drugs varies widely.
Polygamy would be legal.
Unlikely. Polyamory is fine in a "not my thing but whatever floats your boat" kind of way, but polygamy has almost always led to abuse, whether physical, emotional, or financial.
Homosexual marriages would be allowed.
Yep. nothing wrong with that.
Public sex and nudity would be allowed. Porno would be allowed on all public TV channel that any child could watch.
I suspect you will find atheists differ on the first point. Public nudity probably shouldn't be punished. (Which is not to say everyone would take their clothes off -- for one thing, not everyone wants to.) Public sex... well, you'll find very liberal people who believe that such a thing would be forcing others to take part in your sex life.
As for the TV thing... well, I don't exactly want Vivid Video on prime time, but boobs on broadcast TV? Bring it on. Most other Westernized countries seem to have no problem with it.
School would be optional at all ages.
Who believes this? Maybe a few anarchists and extreme libertarians. But... lots of Christian fundamentalists.
Handicapped and the mentally ill children would be allowed to be killed by their parents because they would be considered a burden to society.
Uh... no. Those who have advocated that have been either extreme religious nuts or extreme elitists.
All abortions would be legal at all stages.
As it was until the banning of partial birth abortion. Abortions should certainly be discouraged, but not banned under any circumstances. (As someone who was born to a teenage mother and adopted, this was a very difficult conclusion for me to come to. I therefore treat it as sacrosanct.)
We'd live in a totally different society.
Yes, we would. And it wouldn't be an atheist society per se -- it'd be nihilistic anarchy. Everyone for themselves, might makes right, and everyone who couldn't operate a gun would be a slave. Last I checked, that was mostly a fantasy of the Right, not the Left.
And after the society collapsed, the military would take over
What military? I'm pretty sure the closest thing to a military in your fantasy nightmare would be some schmuck who managed to buy off a half dozen shotgun-toting thugs with a case of powdered eggs.
and of course it would be run by a ruthless dictator who would run a police state. Yes I'd be willing to bet all these actions would take place eventually.
And no doubt said dictator would be a fundamentalist Christian, right? Okay, maybe not, because that would make you a total wanker. As it is, you're a wanker to begin with because you're just looking for excuses to say "I told you so".
