You have no way of knowing at what point I arrived at the opinions I hold now. You have no way of knowing whether or not I arrived at those opinions prior to looking into things, or after looking into things. To make the assumption that I arrived at my opinions prior to looking into things, or even that I was predisposed to hold the opinions I now have shows your own bias and your own lack of credibility on this subject.
