Gendering: Status signaling for people who don't need to procreate to prosper.

My view is that gendering is status signaling for people who don’t need to procreate.  Who needs to have children when we can get ahead without family and those who do have kids can expect them all to survive?  Gendering displays advance the individual's status and influence in their social eco-niche but not in their original family.  But that doesn't matter because it's not about kids.  I’m not addressing traditional same-sex sex but am speaking to the useful fripperies of gendering for which there is no alphabet big enough.

Evidence of the alphabet:

"Previously, the queer community had a disjointed identity and was referred to as the “gay” community. The abbreviation LGBT itself evolved. It is now disrespectful to refer to the community only as the LGBT community. It is appropriate to use the abbreviation LGBTQIA+ or LGBTQIAP+ to be more inclusive of all identities within the community. The community has also now evolved to be more accepting of a variety of gender and sexual ‘minorities’ that failed to find a place before."

To illustrate what I mean:
Both birds are male but the fanciest one invests in over-the-top display to attract the attention it values. Such birds occupy very small niches where this pays off for them.   The alphabet genders have small niches that work well for them. 

  The quieter one actually sits on a nest and shares duties hatching the babies.  You see a lot of robins because this works well and supplies lots of baby robins to populate future lawns and forests.
