Ironic, or just an idiot?

I am trying to decide if this person is actually smart and making an attempt to be ironic, OR a complete idiot because the sticker preaching about speaking English uses "butt" instead of "but", and "your" instead of "you're".

Judging by the fact that they have a Wal-Mart ribbon and a "God Bless America" sticker, I have to vote idiot.
