A US anti-equal marriage group, has made a comparison between the date on which the Supreme Court struck down a key part of the Defense of Marriage act, and that on which the attack on Pearl Harbor took place, saying both will “live in infamy”.

The American Decency Association (ADA) has also published a separate column calling gay sex “disgusting”, as well as noting the date of the Supreme Court ruling in Roe v Wade, which was a landmark case for women’s rights to abortion, reports Right Wing Watch.

In a column posted on the day of the Supreme Court ruling on DOMA, Lisa Van Houten wrote: “As we look back on history there are dates which we now see were crossroads, turning points for nations and cultures. [Independence Day] July 4, 1776; [Date of Normandy landings] June 6, 1944. [Pear Harbor] December 7, 1941; [Roe v Wade[ January 22, 1973. Battles fought, decisions made – some establishing goodness and justice, others are dates that 'will live in infamy.'

"I believe today, June 26, 2013, is the latter. A date when the United States Supreme Court ruled in favor of same sex marriage, and undermined true marriage – one man and one woman – which was instituted, not by any government, but by God."

She went on to claim that, as a result of the DOMA rulings, "pastors [may] be prosecuted for preaching what God’s Word says regarding homosexuality and refusing to perform same sex ‘marriage’ ceremonies”, gay people will become a “protected class by the government”, and that organisations such as the ADA will lose their tax-exempt status.

In a later column, the organisation’s president Bill Johnson, called gay sex “disgusting”. He wrote: “Years ago when network television began shoving their pro-homosexual programming down our throats, some ministries began early to oppose the pro-homosexual movement.

“I thought seriously? What’s to worry about? How many men would stoop to having intimacy with another man? How disgusting. How unnatural.”

Johnson recently wrote an article attacking basketball star Magic Johnson, for speaking out in support of his gay son who publicly came out.
