It is wrong to judge someone else's family dynamic.
Dave meets Ken who tells Dave that both his parents are transgendered men.
Dave wants to react to Ken's statement.
Dave tells Ken that it's refreshing to see someone raised by a non nuclear family once in a while.
Dave tells Ken that he finds that quite frankly disgusting and that men shouldn't be with other men while raising a family.
Ken is happy to see Dave appreciates the uniqueness of his family situation.
Ken is offended that Dave has such archaic views and is angry with Dave's disrespect.
