I mostly appreciate where you're coming from here, but I think the greater problem is that paedophile accusations, as a concept, have become so diluted that the immediate repulsion has worn out. It's not 4chan pornography causing that, it's the endless supply of melodramatic rambling Google docs, Twitlongers, and even random rumours and dramamongering that have taken what should be the most damning thing you could say about a person, and trivialised it into something petty. In the Current Year, when I hear that someone is a paedophile, it could mean they are a 22-year-old streamer with a 19-year-old girlfriend, that they retweeted fanart of an ambiguously-aged anime character, that they had an underaged partner who lied and said they were older, that they made a joke that looks bad without context, that they were manipulated or groomed into posting dark material for someone else's gratification, or, in seemingly much-rarer situations, that they are sexually attracted to children.
The number of false accusations a typical person will encounter online far outnumber the genuine ones, so it's hard to be surprised when someone's initial reaction to seeing something like this is to comb through everything and exhaust every single possibility they could be innocent, even farfetched ones, before assuming guilt. I found myself doing it subconsciously even though I trust the forum staff to vet information for accuracy and know for a fact you have absolutely no reason to lie about this, and it wasn't until I broke down the facts for myself
like this that it sunk in how bad this situation really is.
In an honest world we'd still have that violent repulsion upon hearing someone's a paedophile and act immediately, but letting that feeling take over in the real world we live in would result in a lot of innocent people having their reputations ruined for nothing, and would play directly into the hands of abusive people who use life-ruination tactics like riling up a mob in bad faith to hurt their victims. It's hideous all around, but when someone's gut reaction is to start picking everything apart and speculate on ways it might not be as bad as it looks, I
get it.
