If countless generations under Levitical role restrictions for hundreds of years is acceptable, why would one lifetime of gender-based role differences be dehumanizing?

Mike argues that if generations of Israelites could be permanently excluded from priestly roles for hundreds of years without being less human, then a woman's one lifetime of role differences (before co-reigning with Christ in eternity) cannot be dehumanizing. The Levites' role was based on genetic lineage (nature), not ability, yet no one considers non-Levites less human.
