Oh, but you can bet that I will actively criticize your assertions....
I'm actually the lesser enemy. I just criticise without pushing any agenda. 'Cause none of Ayn, Upton, and Kropotkin have fully convinced me.
Don't get me wrong, skepticism, along with free thought, free inquiry and the like, have a great history, esp. in the age of enlightenment/age of reason where the 'accepted' authority of kings and religions were questioned openly for the first time in a very public manner.
And skepticism is a factor in the right approach in addressing subjects, but to make it into a philosophy of itself, is, imo, a mistake for the reasons stated in the link. I knew that before I ever read Rand :- )
Skepticism is a bit like being an All City quarterback in high school. It doesn't play that well after graduation. You might be able to start a furniture store with your fans, but you better learn some concretes about running a business, or you're going to get sacked by reality. :- )
Skeptics push skepticism as an agenda. I've met a few.... lol.
