Religion is going to fail in today's world even with 0% Pornography
According to Quran, even Sahaba were not able to control their lusts for even 30 nights of Ramadhan.
Initially it was prohibited to have sex with the women in the 30 nights of Ramadhan. But it was too much for Sahaba to control upon them and they secretly started going to their wives.
At the end Quran gave them them permission to have sex during the nights.
Surah Al-Baqarah (2:187)
“It is made lawful for you to have sexual relations with your wives on the night of As-Siyam (fasting). They are Libas (i.e., body-cover, or screen) for you and you are Libas for them. Allah knows that you used to deceive yourselves, so He turned to you (accepted your repentance) and forgave you. So now have sexual relations with them and seek that which Allah has ordained for you
In today's world, the age of marriage of men is about 30 years, while girls are being married at 24 years.
If Sahaba (who were the beacons of lights and Iman) were unable to control upon themselves for 30 nights, how then the Muslim parents are going to expect their boys to control themselves for complete 30 years?
And Sahaba were even unable to abstain from sin during the short period of the wars:
Sahih Bukhari, Volume 7, Book 62, Number 13o:
Narrated 'Abdullah:
We used to participate in the holy battles led by Allah's Apostle and we had nothing (no wives) with us. So we said, "Shall we get ourselves castrated?" He forbade us that and then allowed us to marry women with a temporary contract
Sahih Bukhari, Volume 7, Book 62, Number 13h:
Narrated Abu Huraira:
I said, "O Allah's Apostle! I am a young man and I am afraid that I may commit illegal sexual intercourse and I cannot afford to marry." He kept silent, and then repeated my question once again, but he kept silent. I said the same (for the third time) and he remained silent. Then repeated my question (for the fourth time), and only then the Prophet said, "O Abu Huraira! The pen has dried after writing what you are going to confront. So (it does not matter whether you) get yourself castrated or not."
Muslim societies have no other way to save their children from sins, except for marrying them just after they get adult. But practically it is almost impossible in today's world. It was not even possible in the earlier times when due to poverty Prophet Muhammad got married at age of 25 and Abu Huraira was also poor and was not able to marry a woman.
Other Muslim excuse is this that they could save their children from sin by compelling them to FAST continuously for several years from adulthood till marriage. Again they are going to fail in it.
Firstly they could not compel their children for fasting for so many years.
Secondly, it is wrong claim that fasting stops the sexual lust.
I was a Muslim myself for many years. I fasted for many years too, but it never decreased my sexual urges during Ramadhan.
Actually we have ample proof that this claim is false from Quran itself when the "Fasting Sahaba" were unable to control upon themselves for only 30 nights of Ramadhan and they secretly went to their wives.
Therefore, in Islamic societies will keep on seeing the rape of children in Madrissas.
And we also keep on seeing the sexual frustration in the Islamic societies.
