Entertaining thread so far
I agree entirely with Boulder (almost)

, particularly about the hypocracy and the cutting the crap. I say what's on my mind, and it shocks people.
I also agree with Gale about the monogamy thing. I have expressed this in public before and you get nothing but strange stares. Try suggesting that you want to have sex with multiple people, or even multiple people at once, or anything at all out of the ordinary, And people look at you as if you are a freak (Of course, doing this in a sincere, well thought through idea, not as a "Hey, I'm a guy and its my social duty to tell everyone that Sex is the only thing on my mind: That being another social convention that annoys the hell out of me)
I hate the hypocracy that surounds sex: "I am the only person in the world who has sex" is basically the mind set. Do your parents have sex? "Ohhh, no...thats gross!" Do your best friends have sex? "ooohhh no, that's gross! I don't want to think about that!" etc
People, get over it. We all have sex. Everyone. It's not 'gross' when u do it, so why is it gross for everyone else?
OK, enough ranting.
Children being treated like lessers
What i mean by that, is that we raise children with such conflicting hypocracy all their lives, and then wonder why they grow up to be liars and not perfect little angels...
Do as I say, not as I do.
"Why do I have to do that" ---> "Because I said so"
The dictatorial attitude of parents annoys me. If parents are so certain that what they are doing is right, then they should be able to explain to the child their reasons (of course, I understand sometimes it gets tiring, but I maintain my point). If you try raising children as people, giving them the credit as individuals that they are due, then they may grow up into individuals, who feel deserving of respect, and able to give respect.
Deciding that teenagers are trouble
Following on from the Children thing, it is so firmly in the mind of society that every child becomes a pain in the ass when they become a teenager. Why do you think this is? Probably because the parents have raised a hypocritical litel child, and they assume the worst of the child, and so start applying unfair rules, and start ignoring everything the teenager says, assuming its all lies. They then wonder why the teenager gets worse over time.
I guess u could reduce both of those points to the social 'Moral convention' of "Respecting your parents" as if they automatically should be treated as gods, and never questioned.
Any rational parent here would be the first to admit that they are far from infallible.
i talk too much. Bye.
