It seems disingenuous to mix Agnosicism with Atheism. Both are utterly different - one makes a knowledge claim (atheism) while the other is in a position of neutrality or indifference (agnosticism)
Sure, but making a knowledge claim doesn't make it any less objective or wise than being neutral.
I can say that there is definitely not a red 1982 Chevy Silverado orbiting Jupiter and that's a "knowledge claim", yet someone who says they're not sure or are neutral about my claim don't hold a superior position in any sense and would, in fact, look a little silly given the lack of evidence against it.
