A post at Our word is our weapon takes apart one of the increasingly outrageous posts emanating from the Adam Smith Insitute blog. It appears that the author of this site is also one of those whose contrary views are deleted from the ASI blog.
I suppose it's easier to pretend you're 'winning the argument' if you systematically exclude any dissenting views.
As I said in a comment on the post, the ASI appears to be succumbing to groupthink but they are probably not alone in that. One of the common problems in Blogistan is that bloggers tend only to read those with whom they agree - couple that with treating blogs as private property and you can rapidly descend into self-delusion.
