Whatever you think about Kos, his essay on Cato Unbound is at least thoughtful. Not particularly well thought out, but thoughtful. He doesn't call names and he doesn't insult anyone. For now.
One of the reasons that I took Cato Unbound off my blogroll is that it has typically deteriorated into a shouting fest of name calling shenanigans. I thought their first topic went very well, but the ones that followed have been less than scholarly debates.
After the rebutal essays are published I'm putting even odds on Markos becoming completely unhinged which should, all things being equal, put an end to this Democratic Libertarian BS once and for all.
