Sport is often credited with having the ability to break down social barriers, and never more so than during NBA journeyman Jason Collins' big coming out party this week.
Collins' brave decision to publicly reveal he is gay has been hailed as a landmark moment for professional sports in the United States, with the big centre the first openly gay athlete who is still active in one of the "big four" pro sports - the NBA, NFL, NHL and MLB.
When you think about it, it is a little strange that Collins has been so widely lauded for simply being honest. The fact that it is such a big deal only makes league hardman Ian Roberts' decision to come out back in 1995, when he was at the height of his career with Manly, seem all the more gutsy and courageous.
Eighteen years on, homosexuality remains one of the last real taboos in sport.
Late last year, when New Zealand was still debating the marriage equality bill, I pondered why no sports stars were willing to get involved with the campaign to legalise gay marriage after Mike King's repeated attempts to rally support from the sporting community.
