With the holiday shopping season in full swing, the Salvation Army's Red Kettle campaign is once again coming under intense scrutiny from lesbian, gay, bisexual and transgender (LGBT) rights advocates.

America Blog is asking LGBT shoppers and allies to give downloadable "vouchers" to Salvation Army bell ringers in lieu of cash in an effort to let the organization know that "bigotry is not a Christmas value," according to blogger John Aravosis.

"The Salvation Army discriminates against gay people, and discriminating donors should find another charity this Christmas than evangelical bigots who advocate against our civil rights," Aravosis writes. "And not just that –- they’ve actively lobbied against pro-gay policies in a number of countries as well."
