Tbh very rarely are debates you find on youtube well structured and really fact based. A lot of times its more about arguing semantics or finding logical traps in the others rhethoric more so than spreading knowledge on the subject. And very rarely does it change minds. Maybe it did for you but believe me when I say that is an exception. Generally vast majority of the audience just comes to affirm their believes through a vehicle or a mouthpiece. Its unfortunate but it is what it is.
