Making outlandish claims with no evidence to back them up

I was just reading a comment on The Dilbert Blog where a person made the claim "Government has a significant role to play in a modern, market based economy. Those that think otherwise are badly mistaken."

Yeah, I see nonsense like this all the time, yet the person making the claim never backs it up with anything real. We are supposed to bow to their wisdom and just accept the claim as if it is a given, handed down from above.

You can have a "market", or you can have government playing a "significant role". You can not have both no matter what you believe, and no matter how much time you have spent as a priest for The State in its indoctrination camps.

Added: Yeah, it's "just" The Dilbert Blog, but if any of you out there care to drop by and give me a hand I'd appreciate it.
