The Christian Science Monitor published an article, specific to Sweden, but offers some valid ideas to think about. For example, should we use gender neutral identities with children?
The article is obviously biased towards theologic doctrines, but we can agree that we have two genders and there will always be a separation between the two and understanding those differences while promoting equality is the key to advancing socially.
Boys will never have babies and I do not see “gender neutral” bathrooms in public places among other examples, so there is always going to be male and female identification markers. Again, I believe teachings of gender equality rather than the use of gender neutral terms will help people express altered identities later in life should one express the desire to do so.
