Most of us are fairly resilient on here. There's always the 'off' switch, or taking a break if you don't appreciate the personal comments. In my opinion they are an unwelcome part of discussion, as they distract from the debate.
But as a whole I enjoy the free speech and differing views. It would be far worse if it were an echo chamber, full of sterile comments.
And for ganging up, it happens. not just to Wisbech, but to a few others. It is a slightly distasteful element, but it's human nature for the most part. I think Wisbech gives as good as he gets, and most interactions with him are usually dolloped with a large spoonful of farce/irony/humour
But back to the topic. I think that politics is going to heavily influence the outcome of an investigation. I think all the information out there is certainly subject to influence and interpretation at the moment. The key witness being dead, gives an opportunity for different parties to fill in the gaps,...probably with bias.
