it's the internet. what do you expect?
(´・ω・`) Real talk, though. I think it's very sad that it's this way -- it's a given that people will treat it this way, especially because of the (to borrow the phrase) 'safety blanket of anonymity' and the detachment of the situation. It's a surreal situation being posted about by some stranger they understandably don't have much compassion for, so they didn't take it seriously. However, any of them who were taking it seriously and trolled forgot to have compassion for Denko in their eagerness to punish the OP for not listening, and in the end just spread more pain and got 'Denko' hurt even more (or would've lmao if she were real). Obviously they aren't fully at fault here since (´・ω・`)-kun mostly ignored them and selectively listened to the bad advice, and I'd in no way venture to say (´・ω・`)-kun shouldn't be 100% blamed for his actions (because I have little but condemnation for people who stalk and harass others), but that that bad advice was given so much in the first place is a little sad when you consider the context.
What it reflects is what we know to be reality, yes, but a
disheartening reality -- that people don't take the internet seriously. So many people have very meaningful connections on the internet because they're able to remember that the internet is a way of connecting them to people just like themselves, and they don't automatically discard the value of interactions conducted on the internet just because of the medium. In short, they treat the internet as a way of broadening their horizons, rather than choosing to limit them artificially and detach themselves from humanity. You're (in the general sense, not referring to you as in Redew ^^) not better than the people you talk to on the internet. They are people, same as you, with valid feelings, and chances are they're the exact same people as you'd be dealing with offline who sometimes like to go online, just like you. Not to mention many people who are housebound for lots of reasons (disability, severe social anxiety and/or hikikomoriism, living in a very remote area, etc.) make use of the internet as one of their only regular ways of keeping in touch with the world, and the internet is something that brings them together because they can bond together over their isolation. Which is one way people like this end up on 2chan, btw -- a lot of hikikomori spend their time on boards like 2chan, and you'll notice that the OP reiterated many times how he doesn't have any friends except 2channers, etc. There are a lot of scary threads on 4chan, Reddit, etc. too! So, yeah, while this is reality, it's not a good thing that should be encouraged or passively normalised.
Also goes for when people encourage others to kill themselves, etc. in advice threads on the internet. Don't do that. It might seem funny to you... if you think other people's lives are less important than your temporary amusement and if you're good at compartmentalising, cognitive dissonance, and forgetting that there's a person just like yourself at the end of your screen, except that person is actually going through problems and isn't fortunate enough to be in a place where they can be like HA HA TELLING A PERSON WHO IS DEPRESSED TO KILL THEMSELVES IS FUNNY (´・ω・`) well that's my rant for today.
Sorry, I know it wasn't very well-worded, but I'm super tired.
