Scott Arnold of Oskaloosa, a university adjunct professor who is gay and a Democrat, said the Republican presidential candidate's response during a Tuesday appearance at a coffee shop in Oskaloosa "doesn't inspire hope at all," The Des Moines Register reported Wednesday.
"When you ask somebody a question and you expect them to support all Americans and have everyone's general interest," Arnold said. "It's a little bit frustrating and disheartening when you're told to support the other side. That he doesn't' need your support."
Gingrich, who has a half sister who is a lesbian, has previously said in Iowa that same-sex marriage "is a temporary aberration that will dissipate," the newspaper said. He has advocated for a federal constitutional amendment that would deny marriage rights to same-sex couples.
