Re: What is your argument against secularism?
porn itself is flatly against the ruling of guarding one’s modesty, lowering one’s gaze and guarding their private parts as ordered in the Quran. Anyone who indulges in zina or alcohol himself/herself or promotes it (porn is a mere promotion of zina) by being part of the trade, business related to either of these has been shunned according to the Sunnah.
And even according to Sunnah and the Holy Quran there is no set age of marriage.
