This is kind of my stance towards the hard anti-NTR crowd too. If you're that disturbed by the concept of NTR, it likely means you have some insecurity or anxiety about the real-life situation. I find it super unlikely that any girl I see would cheat on me. If she did, I'd be disappointed, but get over it by going out to crack some other girls myself. I'm unable to be an NTR fan simply because that anxiety isn't in me. For the same reason, I'm unable to be disturbed by it.
