I think it's important to show the level of depravity demonstrated against the McCanns on social media, a hatred which time and again is denied to exist by some of the supposedly more rational "sceptics". I also think it's worth asking why some of these supposedly rational "sceptics" actively choose to have such despicable posts on their timeline by choosing to follow the individual who made those threats. Even more worrying to note is that "sceptic" champion and voice Sonia Poulton appears to be supportive of the individual who made those tweets (not of those tweets specifically but of his campaign for "justice" - his own as well as Maddie's it seems).
I'm not going to apologise if repeating these vile tweets here makes some people uncomfortable - they need to know that real, serious threats are being made against the McCanns and they play a role in it themselves, by encouraging people to believe that the McCanns are guilty of something very bad and encouraging them to take action. The person who made those death threats retweeted numerous tweets made by several well-known sceptics, all of them based on innuendo, gossip, myths and outright lies. Anyone who devotes a large part of their life to disseminating anti McCann propaganda has to take some part of the blame when more extreme threats and comments like these appear on social media. It's telling that no "sceptics" that I can see ever remonstrated with this individual about the content of his tweets.
