Broadcasting "Hate Speech" to Aliens?

The quixotic project of beaming tweets with the hashtag #tweetsinspace to the planetary system GJ667Cc later today apparently will be censoring what the designers call "hate speech" from their broadcast.

I quote: “It all goes,” says Kildall, the new media exhibit developer for the Exploratorium. “Even political positions I don’t agree with: ‘Vote for Romney,’ ‘Vote for Obama.’” (All except hate speech, he added. We might not want to betray our baser nature to the ETs.)

However, I would assert that urging anyone to vote for either of the evil tweedle-dee/tweedle-dum twins  Obama/Romney is indeed equivalent to "hate speech." What a polluted abomination we will be broadcasting toward these perhaps innocent life forms. I fear it will be tantamount to proof positive to any sentient aliens out there that there is no intelligent life on this planet. Alas...
