I now feel like I will hesitate to submit a Cato article in the future, and I don't even know what is wrong with them! Basically exactly what the article discusses.
Conservative think tanks posts can definitely stimulate good discussion, but if you don't moderate consistently, the community will eventually form a hivemind politically.
I don't care one way or another about banning, but yeah, people really should not put any weight into what comes out of it today.
Though I do think their opinions may be skewed, I don't doubt the facts they are presenting in this article.
Sometimes Cato has useful studies or data, and then it's worth reading. It's a moderate, academic, economics-colored point of view on the world. I wouldn't call it exciting, but this kind of complete dismissal in a thread about dismissal and silencing of moderate voices apparently looks silly to some people.
Or if you think about it, of course you need much more Philantropists when you have Liberatism :D
