I was particularly irritated by right-wing Christian Wintery Knight's recent post on Obamacare, in which he repeats various dubious, cherry-picked stats and conclusions from a Hoover Institute guy as evidence that the US system is much better than the NHS. Wintery Knight's posts are generally recycled right-wing dissembling, myths and apologetics. I made a quick first comment on his post on Obamacare and then followed up with various links and stats. Wintery Knight responded to first comment and refused to publish my other comments. Apparently he's got form - even editing people's comments before publishing them. I am pretty sure that's not what Jesus would do. The only other experience I have had of having my comments "disappear" was here: Mark Vernon posted on my Radio 3 talk about my Believing Bullshit book, then engaged with me up to the point where I was clearly getting under his skin, at which point my comment "disappeared" leaving Vernon with a condenscending last word. I take a particularly low view of those who set up blogs to give the appearance that there's a free exchange of ideas going on, when in fact there is deleting or even editing of comments to suit the blogger. Any other examples...?
