So yesterday, NBA player Jason Collins comes out as gay. A Jackie Robinson-esque moment, given that no active professional athelete in the United States has ever done the same.
Bryan Fischer of the American Family Association tweets:
Proof they are not "born that way:" Collins' IDENTICAL twin – SAME DNA – is straight as an arrow. sportsillustrated.cnn.com/magazine/news/…

For those of you thinking Fischer has a point, there's this thing called epigenetics – it's the science of how genes express themselves. In a nutshell, people with the same DNA don't grow up to be 100% carbon copies of each other, because genes express themselves differently in everybody. Even identical twins.
