How can One person be This Dumb?

Remember how we all laughed at Sarah Palin for coming up with the word "refudiate" a couple days ago? Well, apparently, it was not so much a slip of the tongue as she honestly thinks that this is a real word:

Then she took that "tweet" down and replaced it with this:

re·fute

–verb (used with object), -fut·ed, -fut·ing.

1.

to prove to be false or erroneous, as an opinion or charge.

2.

to prove (a person) to be in error.

You know, Sarah, I actually would like to refute the "Ground Zero Mosque Plan," if I may. There is no plan to build a mosque at "Ground Zero." No Muslim church or organization owns that land and therefore, they can not build anything there. The land is owned by, I believe the Port Authority, or maybe the City of New York, but either way, there is not going to be a mosque built there.

There is a plan to build a mosque and Islamic Community Center a couple of blocks away from ground zero, that is true. But since the Cordoba Institute owns that land, they can do with it as they wish. Property Rights. Look it up, it used to be a core conservative value.

Never one to just let something drop, Palin has responded to criticism thusly:

No. No we don't got to celebrate it. And Shakespeare coined new words on purpose, not by misunderstanding already existing words. And what the fuck is "wee-wee'd up?" Where the hell does that come from? Never mention Shakespeare again, you stupid, stupid person!
