"...moral is deeply rooted in religion..."
For most, not me. It never was, and never will be. My morality developed slowly over decades using reason for my ethical system, not superstition, not conformity to society. I decide what is best for me, not others. That's a fact - jack!
If it's your opinion that I don't have that right, I must conform, and you will make me, support a coercive system that dictates to me, then you are NOT entitled to your opinion, i.e., I will never grant you moral authority over me.
