My idea of noblility, purity and righteousness is very different from yours.
Let me ask you a couple of question. Do you think a pornstar is righteous, pure or noble? What do you believe to be righteous, noble or pure? I believe that nobility is an absolute rather than a relative concept but I would like to hear your response.
You cannot quantify what is righteous and what isn't. Rather it is quite evident what is righteous and what isn't. I believe that a pornstar is not noble, pure or righteous simply because the pornstar is engaging in sexual intercource with no shame.
We are humans not animals. Religion has been sent down to us to teach that we are different to animals. While animals have instinct and will satiate their desires (ie food and sex) in any way possible, we humans are built in a more dignified and noble manner. Fornication as I have explained earlier has with it many good points yet the bad points outweight the good points.
It is up to us to implement noble acts to be different from animals. By having sexual relations outside of marriage, we are no better than a mere animal who
cannot control its desires.
