Conservative commentator George Will has criticized gay rights activists for acting like “sore winners.”

Appearing on Fox's Special Report with Bret Baier, Will, 72, weighed in on the resignation of Mozilla CEO Brendan Eich.

Eich stepped down as CEO on Thursday over a $1,000 donation to the campaign to approve Proposition 8, California's 2008 voter-approved constitutional amendment restricting marriage to heterosexual couples. Proposition 8 stood until last year, when the Supreme Court left in place a lower court ruling knocking it down.

“In addition to the evidence, redundant evidence, that progressives are for diversity in everything but thought, it's an illusion of a new phenomenon,” Will said. “No one likes sore losers, but now we have sore winners.”

The gay rights movement is “winning,” Will said, with a “speed and breadth that simply takes your breath away.”

“Yet unsatisfied with victory, they seem to want to stamp out and punish people for their previous views,” Will added. (Eich has not discussed his views on the subject.)

Will also chided gay rights activists for being “sore winners” after Arizona Governor Jan Brewer rejected a bill that opponents said would allow an individual or business to discriminate against gay and lesbian people based on their religious faith.
