*As someone previously completely uninvolved in this dispute, I must tell that view about Hiss not being a  Soviet spy is indeed WP:FRINGE. But even if this is not fringe, clearly telling that Hiss was a Soviet spy per majority of scholarly sources (to comply with WP:NPOV) is our obligation. But I am not really surprised. For example, I saw a very long dispute about the question when WWII started, although this is something described in every textbook.
