So the fact that they teach this in school, and I google sin and came up with that in three seconds, is biased and one sided. What side are you on?The fact you are putting the 'funny' icons on posts indicates you are playing a game, trolling in other words. You aren't attempting to put a serious argument forward on anything, you are just trying to mock people.
Posting up a biased one sided source isn't proof of anything and you probably shouldn't take such things literally.
