Best comment from the Gizmodo discussion:

We must not tolerate this arsenic deviant. Our society is based on phosphorous DNA, it always has been, and it always will be. If we allow this arsenic abomination to exist, then what will come next? Silicon? Unobtanium? We must fight for our traditional values, and the rights of phosphorous lifeforms.

Additionally, the research clearly shows the bacteria CHOOSES arsenic, when it can clearly use phosphorous. It is a deviant by CHOICE.

Unite with me brothers and sisters, and write your congressmen demanding a vote on the matter.
