Morality

[Faith No More]

An analogy For example, here in the u.k there has been a big debate on "legal drugs." More people have been experimenting with legal drugs, because they are legal. those people would not use illegal drugs for the very fact that they are illegal.

People are doing legal drugs because they're cheaper and easier to obtain, not because they suddenly feel it's socially acceptable. Besides, drugs need to be decriminalized and hallucinogens legalized.

Similarly, if boundaries on morality were strictly in place it may stop people from engaging in immoral acts, because that boundary was there i.e religion. Once the boundary has been removed, it allows immorality to be engaged in.

You mean like it stopped the pedophile priests?

Well I honestly think I would be a worse person if it were not for religious teachings. As a young boy we were taught religion and "right and wrong" in school. These foundations are present in us even in adulthood.

You are giving religion the credit for morals when they really appeared as humans started to live larger societies to maintain order. Religion then highjacked these morals and claimed them.

Of course there is no evidence to suggest that as a species we were more immoral before abrahamic religions took hold in the world. Mostly due to the fact that the concept of morality had not yet been devised.

Morals most definitely predate the abrahamic religions.

Psychologist Matt J. Rossano argues that religion emerged after morality and built upon morality by expanding the social scrutiny of individual behavior to include supernatural agents. By including ever watchful ancestors, spirits and gods in the social realm, humans discovered an effective strategy for restraining selfishness and building more cooperative groups.[12] The adaptive value of religion would have enhanced group survival

I feel that even atheists who act decently, are going on the religious precedent set before them.

As stated before, religion was only going on the precedent already set, so giving it credit for anyone's morality, theist or atheist, is incorrect.
