I'm not sure whether you're trolling or not, but that's a shoddy argument. A sin is, by definition, an offence against some god. First you have to prove that there is a god; once you've accomplished that, then you have to prove the nature of this god. By that I mean you'll have to prove that this god is a) an interventionist god who cares about the actions of his/her/its creation and b) that the rules set by this god are in agreement with the ones you're claiming (i.e. the Christian ones).
I highly doubt you can do either and so your argument falls apart on the first hurdle. That's a nice little triplet and probably makes for good advertising but, unfortunately, it's just not a good argument.
I do, in fact, believe that. There's no objective reason why anything we do is inherently good or bad or has any meaning of the kind often claimed by religious people.
Now you'll need to prove that If you can't prove it, then the above statements wont work. It depends what you mean by 'wrong.' The concept of 'wrong' is so subjective that I could easily answer that rhetorical question with either yes or no without having lied in either instance. An ultraconservative Saudi preacher probably classifies having lustful thoughts as 'something wrong' -- I don't feel bad when such a thought crosses my mind.
No, wrong is when you feel bad about doing something, even if it sometimes could be "right" with someone else. The thing about it is that it relies to some extent as to the circumstance, plus the fact that different things are wrong for different people.You're also pulling a fairly obvious non sequitur. There's no logical link from 'we have morality' to 'we need god.' There are any number of explanations for the origin of altruism in animals (and yes, it is observed in non-humans as well
) that don't invoke a god. So no, we don't necessarily need god.
I'm not referring to altruism. I'm referring to conscience. Altruism can be fairly easily explained by science; conscience can not. I was responding to your assertion that atheists are somehow offended by the fact that you believe in a god and the conclusions you drew from that. I wasn't making a general comment about liking debate.
It was a fairly silly conclusion to say that we're somehow closet theists fighting the urge to worship your god -- that's an exceptionally condescending view and one of the most irritating traits of some creationists who go around offering people salvation in exchange for a monthly donation to their church.
