Political writing
Card is active as a critic, political writer, and speaker. Shortly after the September 11, 2001 attacks Card began to write a weekly column named variously "War Watch", "World Watch", or "Civilization Watch", depending upon the topic; since late 2008, publication of the column has become somewhat sporadic. The column is published in the Greensboro
Rhinoceros Times and his Ornery American" website. Card is a vocal supporter of many aspects of George W. Bush's leadership style, the war on terror, aspects of the wars in Afghanistan and Iraq, and aspects of the USA PATRIOT Act.
On November 6, 2006, one day before the 2006 midterm elections in the United States, Card wrote an opinion piece for RealClearPolitics, in which he (while being a Democrat) encouraged voters to support the Republicans:
In the 2008 presidential election, Card supported Republican nominee John McCain.
Environment and science
Although he supports government-funded research into alternative energy sources and the phasing out of fossil fuel use, Card has also frequently criticized precipitate action on global warming, and has voiced the suggestion that scientific evidence against global warming is suppressed because global warming has become an academic orthodoxy that discourages opposing evidence.His short story "Angles" also features scientists fearing to pursue research because it would run counter to scientific dogma. Similarly, he has voiced distrust of Darwinism as dogma in opposition to Intelligent Design (which he also distrusts, for entirely different reasons). While criticizing scientists for claiming that Darwinism explains "completely how evolution works," Card also said that "real science does not...and never can...prove or even support" Intelligent Design.
On homosexuality
Card described homosexuality as an acquired characteristic linked to abuse or molestation in childhood. He has called same-sex marriage a "potentially devastating social experiment". He has argued that same-sex marriage is not necessary to ensure LGBT rights because: "Any homosexual man who can persuade a woman to take him as her husband can avail himself of all the rights of husbandhood under the law." He claims that "gay activism as a movement is no longer looking for civil rights, which by and large homosexuals already have." He also says he is against "changing the word 'marriage' to apply to something it's never applied to."
With regard to the acceptance of legal same-sex marriage in Massachusetts and California, Card writes that: "The first and greatest threat from court decisions in California and Massachusetts, giving legal recognition to 'gay marriage,' is that it marks the end of democracy in America. These judges are making new law without any democratic process; in fact, their decisions are striking down laws enacted by majority vote." In the same article he voiced strong condemnation of any government that recognized gay marriage stating, "Regardless of law, marriage has only one definition, and any government that attempts to change it is my mortal enemy. I will act to destroy that government and bring it down..."
Writing of the LDS Church's attitude towards homosexuals, he argues that because the church leaders and prophets teach against homosexual behavior, it is hypocritical for a practicing homosexual to claim to be a church member but still deny that their behavior is sinful.
Card's statements on homosexuality and civil rights for gay people have drawn charges of homophobia.,,,
Card does not consider his views homophobic, stating he does not advocate "harsh personal treatment of individuals who are unable to resist the temptation to have sexual relations with persons of the same sex,"
and that he views homosexuals as "human beings with as complex a combination of good and evil in them as I find within myself." However, he has written that "laws against homosexual behavior should remain on the books, not to be indiscriminately enforced against anyone who happens to be caught violating them, but to be used when necessary to send a clear message that those who flagrantly violate society's regulation of sexual behavior cannot be permitted to remain as acceptable, equal citizens within that society."
In April 2009, Card became a member of the board of directors of the National Organization for Marriage, a group that seeks to prevent the legalization of same-sex marriage. He replaced Matthew S. Holland, one of the founding board members, who is also a member of the Church of Jesus Christ of Latter-day Saints and the son of LDS apostle Jeffrey R. Holland.
