I think the reason for the decay of morals is too much TV. Remember the golden ages before TV was invented? Neither do I. On second thought, I think it must have been women voting. Things started to go downhill when they allowed women to vote.
You seem quite confused. I am not holding everyone blameless, I am only holding God blameless. What man does is man's doing. Oh, and morals cannot be taught, that is impossible. Eventually, every person beyond a certain age has to decide for themselves what is right or wrong, and we see people coming from every type of family and education make different choices. Your comment of Bush liking someone like me shows how genuinely disturbed you are...as everyone here knows what a critic of Bush I have been, especially his mixing his personal faith with his job as president.
You cannot teach morals. A person can behave in a moral manner, and others can be attracted to that behavior and try to emulate it...but morality cannot be taught, no more than a rational thought process can be taught. There is nothing new regarding morality, there are nearly limitless books for people to be read on the subject...but how an individual decides for themselves, cannot be taught. Frankly, atheists like you and the others here have no reasonable explanation for why people are immoral, why ultimately people decide to be immoral rather than moral in their actions.
I'm not convinced of that. Except for sociopaths who genuinely lack any trace of empathy, I think that a "proper" upbringing can provide a moral compass. I think that the area is somewhat more gray than the black and white you believe it to be. A normal child's early, formative years are probably critical in this regard.
Morals are not taught by what authority figures say, but they are learned by those who observe them. Children may be taught to not lie, steal, etc. but when they see their parents, teachers clergymen, politicians, police, etc. doing what was told them was wrong, they get quite confused. Morals are learned by observation mostly, and when children see people doing the opposite of what they are taught, the come to the conclusion that is quite different than what they are taught. Real morality has its basis in what we as people do when we think we could get away with it... If we think we can get away with doing what is considered wrong, but we don't because we think it is wrong on principle...then we are functioning from a moral foundation, not out of fear of punishment for getting caught. That clearly is not what is taught in society at large, and the proof is the massive and rampant corruption in every single institution in society.
So authority figures are inadvertently teaching youngsters the wrong things, and the kids are learning by these adults' examples rather than by their sermons of righteousness and rectitiude. Either way, both teaching and learning are going on, if not exactly as intended.
