From your own perspective, this is problem. From others this isn't. Unless the child is mentally unstable they won't become violent over a video game. They usually learn curse words from their parents not being careful. Unless they are genuinely afraid of something they won't "flinch" when they see it. Lastly, the anti social aspect is usually because introverts tend to lean towards video games to express their feelings without having to talk to others. Tl; Dr- most of what you said is from the scientific traits that the kid has compared to video games that are apparently "ruining our kids". You just got corrected by a scientifically intelligent 16 year old
