You don't need proof; you have the Internet
I’m reluctant to give additional currency to what appears to be a scurrilous fraud, but Wishydig has an interesting post on bogus quotations, “Quotation marks don’t make it so,” featuring a remark attributed to House Speaker Nancy Pelosi:
“You don’t need [G-d] anymore, you have us democrats.”
He has expended some time trying to run it to its source, but, as with so many things on the Internet, sources are elusive. But his research is extensive enough to persuade him that the remark is counterfeit, a canard, a partisan fabrication.
It is bad enough trying to run down the source of authentic quotations on the Internet, where every other remark seems to be given as having come from Mark Twain or Winston Churchill. That is just sloppiness. But the willingness to circulate material that looks dubious, or is manifestly false, is one of the least attractive attributes of our brave world of free-flowing information. A lie has half a million hits while truth is still putting on its britches.
Be careful out there.
