Not just that, the way Datta Talks and Acts is just so childish and such. If he's Supposed to be around 20, you would expect him to act differently, even if he lived completely alone from other humans. I still don't understand why he is being used for Research, its not like he belongs to a foreign Species. I would assume that they wanted to know how humans turn out without any human contact, but I doubt it. For the purpose of this manga, Datta exists only as a fetish, because no human Acts like this.
Fr it's so annoying that people still thinks like that given that tribes and people leaving in the wild continue to exist nowadays. It's not because they don't live in apartments and don't have the next iPhone that they are dumb, childish, and act based on their primal instincts. (Dunno if that makes sense since I'm not a native speaker)
You can't tell me this isn't racist and mygonistic, like come on. Dog-like? Really? An indigenous who fucks the woman first time he sees her and having this "savage" and "tarzan" cliché typa acting. The fl saying shit like "is it my true female desire" or I don't know what like a woman only desire is to be impregnated by a big strong male... nah I'm out. I understand this is just a story, I'm just mad because I'm pretty sure the author thinks that way and some gullible readers will start thinking that way too. Women aren't baby machine in case you thought.
