Widely considered is what you say when you're sort of pretending to be unbiased but your target audience is really all on your side anyway and what you're really trying to say is that something is "widely considered" by you to be true, which of course they already agree with, so it's sorta preaching to the choir. Also, people who are fat but not really can be widely considered. If you use biased phrases like widely considered on Wikipedia, they will burn you at the stake. With a reaction like that, who can resist?
