Firstly, this clown didn't "destroy" anything. He just posted a bunch of very obvious links and aggressive language to "prove" his point. And what did he prove? Masturbation is normal and natural. Brilliant! It's unfortunate that people consider his word as gospel.
Obviously, masturbation is natural and normal, just like sex. Well it's technically sex without a partner. And just like sex, it heavily impacts your mental and physical state.
If you overdo it, it can potentially turn you into a zombie. Which is good for some situations. I used to do it once before every exam to calm down and write for 2-3 hours without any distractions. Helped greatly in sleep as well.
But on the downside, it makes you relaxed and less aggressive for atleast a few hours, or even rest of the day. For some reason, My girlfriend back in the day could immediately sense something's off "you look tired/sleepy/down today" (obviously she didn't know). Also, try lifting or working out in the refractory period.
All of these quirks are applicable to sex as well. But atleast that is meaningful in the context of your relationship.
And if you think all this shit is placebo, maybe you need to read up more about orgasms. The biological driving force behind reproduction cannot and should not be taken lightly.
Tl:Dr - the moron just stated the obvious in an authoritative tone and some other morons celebrated it as him destroying nofap.
