"I do, yes, absolutely," Iguodala said Tuesday on New York radio station Power 105.1's "The Breakfast Club" when asked about the theory.
The veteran NBA forward said the social views of Jackson, who is also an ordained Christian minister, didn't line up with those of Warriors president Rick Welts.
"One particular issue was his views on gender or marriage or what the bible says on your sexuality, and the head of our business, Rick Welts ... he's gay, so there was conflicts with that that was widespread."
Following Jackson's dismissal, Warriors owner Joe Lacob criticized his former head coach, saying Jackson "couldn't get along with anybody else in the organization."
Since the Warriors' coaching change to Steve Kerr, Jackson has been working as a broadcaster with ESPN/ABC. Golden State has reached five straight NBA Finals after Jackson's departure, winning three championships.
