Jeremy Irons has some interesting ideas about gay marriage. If it's legalized, then "could a father not marry his son?" the Academy Award-winning actor asked in a Huffington Post interview. Sure, incest would presumably still be illegal, but in Irons' view, "it's not incest between men. Incest is there to protect us from inbreeding, but men don't breed." In this hypothetical future, fathers could marry their sons in order to skirt taxes when passing on their estates to their sons-turned-husbands. Irons says he doesn't "have a strong feeling either way," although he also worries that gay marriage might "debase" marriage.
