Columbia Sportswear has backed a proposed gay marriage ballot initiative in Oregon.

The Washington County-based publicly-traded manufacturer of outerwear and sportswear is the largest company to support the proposed 2014 initiative that seeks to repeal the state's 2004 ban and legalize gay nuptials.

CEO Tim Boyle told alternative weekly Willamette Week that he'll personally support the measure.

“It doesn't make any sense to exclude people from the constitutional rights they should have,” Boyle said. “Frankly, this should have happened a long time ago.”

Boyle said that he independently decided that the company would back the measure.

“It was not a difficult decision,” he said.

Supporters began collecting signatures in August and have until next summer to collect the 116,284 valid signatures needed to qualify for the November 2014 ballot.

If the measure is approved next year, Oregon would make history as the first state to repeal a constitutional amendment limiting marriage to heterosexual couples.
