Why my tag for mothers is "motherhood" and my tag for fathers is "fathers."

Having just said that it "means something" that The New York Times put its article about Jason Patric's fight for the rights of sperm donors in its "Fashion & Style" section, I'm sensitive to the meaning of what I've long recognized as a strange lack of parallelism in this blog's tags. I've never bothered to look up the answer before, since I know it must have to do with the first post that seemed to need a tag on the subject, but now I'm interested in the specifics.

The post that led to the creation of the "motherhood" tag was "Brought up by a rabid feminist who thought motherhood was about the worst thing that could happen to a woman" (May 24, 2008). Obviously, the word "motherhood" was in the quote I used as the post title, so that preempted more subtle thinking on the topic, but what got enshrined in the tags was the abstract concept "motherhood," not the collection of human individuals who are mothers.

But now I'm puzzled, because the first post with the "fathers" tag also had the pre-existing tag "motherhood": "We bad moms are happy to confess our sins because we're confident..." (May 15, 2009).

This means that my long-standing lack of curiosity over the lack of parallelism was based on an incorrect assumption. Feel free to psychoanalyze me on the subject. Options: 1. Althouse elevates mothers to an ideal realm but leaves fathers in the mundane and concrete real world (and this means all kinds of things about what she thinks about gender politics and gender difference). 2. Althouse prefers simplicity, so she picked "motherhood" because it was right there in the quote and "fathers" because it's simpler than "fatherhood" (and never changing "motherhood" to "mothers" was itself a matter of keeping it simple).
