Lincoln Lover is one of the LGBT-themed episode of American Dad!
Stan is not called on by his local chapter of the Conservative Republicans to speak at the Republican National Convention. After watching a surrealist play about Abraham Lincoln, he decides to write and perform his own play about the first Republican president to return to the original values of the Republican party. Stan's play, a one-man show, depicts a very close relationship between Lincoln and his most trusted guard. The play becomes extremely successful as many homosexual men come to watch though Stan apparently does not notice the gay overtones of his play. The Log Cabin Republicans invite him to speak at the convention; however, it is not until an LCR party that Stan realizes that the members are gay. He is won over by an elaborate musical number ("We're Red and We're Gay") and begins acting more and more like a homosexual male.
Steve, who has been deeply indoctrinated by Stan in the belief that all gays are evil, tries to "save" Stan and reveals to the LCR Stan's previous anti-gay activities (such as participating in the "7th Annual Anti-Gay Palooza" with Pat Robertson). Stan is uninvited from an LCR cruise and not allowed to speak at the RNC because he is perceived as homophobic so he decides to sleep with a man to show "the LCR ... I'm one of them." He goes on a date with Terry (who is mad at Greg and has declared "open season") but fails to become aroused when they reach the bedroom. Terry tells Stan that homosexuality is not a choice, contrary to Stan's belief.
At the RNC, when the Conservative Republicans' speaker is kicked out because her second car is a Toyota Prius, Stan speaks for the Republicans. In his speech (when he sees the Log Cabin members not being let in), he states that they are not gay by choice but nevertheless are Republicans by choice and they should all band together to direct their hatred of gays to fight Democrats who choose to be that way.
