Monday was a groundbreaking day for all sports, not just basketball, when N.B.A. player Jason Collins became the first professional athlete in a major team sport to come out as gay. It was a moment that many had been preparing for and anticipating for a while, a door that finally opened and began a process that will make it easier for others to come out in all sports someday.
And it wasn't hard to see the immediate impact of that opening sentence in the Sports Illustrated column authored by Collins: "I'm a 34-year-old N.B.A. center. I'm black. And I'm gay."
President Barack Obama personally called Collins and First Lady Michelle Obama tweeted about it; President Bill Clinton put out a statement. Athletes and others in the N.B.A. and N.F.L., Major League Baseball and tennis, among others, were quick to show their support as well with tweets and official statements from Kobe Bryant to the Boston Red Sox, who invited Collins to throw out the first pitch at a game at Fenway Park.
What was missing from this national conversation? Nascar.
