A possibility Groothuis ignores: role can be associated with nature but not grounded in nature — God assigns roles by association, not by saying one nature is inferior.

Mike argues for a key distinction: role can be associated with nature (connected to being male or female) without being grounded in nature (implying inferiority). Like arbitrarily grouping people by who has buttons on their shirt, the grouping is associated with a characteristic but does not imply those without buttons are lesser.
