Obama White House censors government petition

Yesterday, there was an official petition recognizing the awesomeness of tacos posted on the White House petitions website. Today, it is gone.

"I just set this up because it’s important to always remember that what people do on the internet should never be taken seriously," the petition's author said.

Despite gathering tens of signatures, however, the White House took down the taco petition.

Question: Is this...

a) Big Brother censorship

b) racism

c) all of the above?
