Agnosticism is a perfectly respectable and tenable philosophical position; it is not dogmatic and makes no pronouncements about the ultimate truths of the universe. It remains open to evidence and persuasion; lacking [religious] faith, it nevertheless does not deride [religious] faith. Atheism, on the other hand, is as unyielding and dogmatic about religious belief as true believers are about heathens.
Sidney J. Harris

It’s not been uncommon in history for agnosticism and agnostics to be denigrated for their position. Both theists and atheists have alleged that agnostics are just “sitting on the fence” and refuse to commit themselves on an issue of vital importance. Such attacks have, by and large, been the product of ignorance as to what agnosticism really is.
