To me, the parents' reaction confirms the homophobic bias, especially the father's reaction. They could just have said something comical like "finally, he's bringing somebody home", "finally, he's out of the closet", "I'm so happy he's happy" etc, and embrace the comically gay situation, allowing the people laughing about the gay situation to laugh, and the gay audience to witness a "happy ending" that doesn't degrade the comical nature of it all. The big bad enemy could also have been a Beholder or a Lich, etc. But no. It's an orc stud, because the fact that it's an orc stud is the point.
