...but apparently it's still real easy.
For example, if you were to insinuate that the "Porkulus" bill was so stupid that a chimp might be able to think up a better one, then you're obviously secretly calling the President a monkey, and are therefore a racist.
Or, if you were to object to veneration of the chOsen One on "Washington's Birthday (observed)"*, then you'd be a racist.
As an aside, I think calling it "Presidents' Day" is a dumb idea. Sure, it's easier to fit on a calendar or a sales flyer than "The Holiday Used To Give Government Workers A Monday Off In February", but the official name of the holiday is still "Washington's Birthday". Back when the average American IQ was still in the triple digits and you had to pass a history class to get out of the third grade, people understood that when someone said "Presidents' Day" (note the plural possessive location of the apostrophe) that they meant "Washington & Lincoln's Birthday". In these times of Who Wants To Marry A Survivor Idol Biggest Loser?, there seems to be some confusion amongst the monosynaptic, who think that it's "President's Day" and is set aside for adulation of Presidents in general or whatever showhorse won the most recent popularity contest specifically.
* This is the correct name for the holiday, BTW...
