Franklin Graham, the son of evangelist Billy Graham and head of the Billy Graham Evangelist Association, has called on followers to stop doing business with gay-friendly businesses.

Graham said in a Facebook post that the Billy Graham Evangelist Association was moving its accounts from Wells Fargo to another bank because it featured a gay couple in an ad. He also pledged to shun Tiffany & Co. for the same reason.

“Have you ever asked yourself – how can we fight the tide of moral decay that is being crammed down our throats by big business, the media, and the gay & lesbian community? Every day it is something else! Tiffany's started advertising wedding rings for gay couples. Wells Fargo bank is using a same-sex couple in their advertising. And there are more,” Graham wrote.

“But it has dawned on me that we don't have to do business with them. At the Billy Graham Evangelistic Association, we are moving our accounts from Wells Fargo to another bank. And guess what – we don't have to shop at Tiffany & Co., there are plenty of other jewelry stores. This is one way we as Christians can speak out – we have the power of choice. Let's just stop doing business with those who promote sin and stand against Almighty God's laws and His standards. Maybe if enough of us do this, it will get their attention. Share this if you agree.”

Many commenters on Facebook noted the irony of the post, asking Graham when he planned to stop using the social network over its support of marriage equality.
