The subtle nuances of NTR have obviously flown over your head. It is a highly compelling commentary the relationships between men and women. The cuck, aka beta male, is btfoed by the alpha/sigma male in a raw display of reality. While the female is often portrayed as short sighted, stupid, and slutty, all the things which modern stories shy away from. NTR thrusts the an alternate perspective of the world onto you like a mighty Atlus thrusts the earth into the sky. With divorce rates skyrocketing people are waking up to the true nature of relationships and the faults of the opposite sex. NTR is a logical consequence of this and it will continue to advance until morality has been restored, and in that sense it is a necessary evil. It is the modern day cautionary tale and the future of all literature as we know it.
I'm in a good mood, so I'll give you this. But remember, great power comes great responsibility.
