No. Morality is rooted in objective reality. Morality is causal and is defined by results.
God gave man three ways to know him. You can blow off the first two if you are a non-believer: scripture from the prophets and from Jesus himself. However, the third way is through nature. And this nature and the consequences of decision of nature dictate what is moral.
No.
Morality is rooted entirely in the presupposition some higher power defines what is correct for human behavior.
A greater number of "atheists" and "pagans" adopt the same hackneyed tenets of a faux Judaic-Christian ideal (golden calf). They also subscribe to the Judaic fetishism of "sin," but will fight to their death in denial of it. Most of them are so wrapped up in their own polemics that they have become nothing more than pathetic anti-Christians with the same false hypocritical philosophy.
They just slap a new label on it hoping nobody will notice - - they replace the idea of "avoiding sin" with "morals."
But, since we are all properly obeying the * modern interpretation * of the First Amendment, good & evil isn't the question... Good & bad, right & wrong, etc., etc., ad nausea; are all inherently religious ideals.
The modern interpretation of the First Amendment (according to the liberal-tarians) says government must exorcise all traces of religion and theism from itself. Therefore, government must never consider issues of morality and right and wrong...
So, it becomes a question of benefits versus costs.
Fetus killing has its benefits to society, especially if you like to sleep late on Saturdays. But it also has its costs as well. Society (by which I mean, whoever manages to seize power) needs to evaluate these costs and decide accordingly.
The mythical rights of men and women are also meaningless. The very concept of rights is also founded in religion. Since the enlightened person is freed from any superstitions about some "God," they are free from having to worry about "rights." Only raw power counts and humans are just meat puppets for the powerful...
However, the third way is through nature. And this nature and the consequences of decision of nature dictate what is moral.
Might makes right. See above...
