You can usually safely dismiss sentences that start with “It’s widely accepted that…” because if it were actually true, they wouldn’t need to hedge like that. The usual reason to start a sentence like that is when it isn’t as widely accepted as they claim, but they would like the reader to believe that it is. When something is widely accepted, you can just say it without the weasel words.
