Jason Collins made history on Sunday when he signed with the Brooklyn Nets and played in a game as the first openly gay player in the major professional sports. Several weeks ago, Mizzou football player and NFL draft pick Michael Sam came out as gay as well. While there has been plenty of ignorant backlash and existing discrimination, we are heartened to see several hugely respected and popular star athletes speak out in solidarity and acceptance. Former Celtics teammate Paul Pierce was quick to voice his support for Collins, and star quarterbacks Colin Kaepernick and Cam Newton come out and say that as far as they're concerned, Michael Sam is welcome in their locker rooms and on their playing fields. Huh. Seems these professional athletes seem to think that what matters in the arena is athleticism, not sexual orientation? Imagine that, and kudos to these influential players for supporting tolerance and progress in the highest echelons of our hallowed sporting pastimes.
