If there’s a linguisty person in my followers, can you explain a thing for me

 I know there’s a reason that trans woman needs to be trans woman and cis woman needs to be cis woman so as not to imply trans women aren’t women (and same for trans men and cis men), but chairwoman can be chairwoman, and englishman can be englishman, and frenchmen can be frenchmen, and boatman can be boatman, and cowgirl can be cowgirl, and firewoman can be firewoman, horseman can be horseman and so on but I can’t articulate what that reason is and can someone please explain it? Does this form only apply to professions and nationalities?  Like it makes sense but I can’t explain the rule that makes it make sense.

Also how come its only Frenchman and Englishman, why isn’t it also a Swedishman or a Mexicanman?

The idea that there’s a single “Cause” of different sexualities or gender stuff is really weird actually

Like… there are probably a huge number of things that result in creating LGBTQ people, in utero, genetic, early experience, and like there can be a huge number of each of those that result in gender or sexuality stuff in a huge variety of ways.  Like some might be endocrine some might be neurological some might be psychological some might be a bunch of other stuff.  The idea that there must be one single mechanism for this stuff is really pretty obviously wrong.  There are probably a whole bunch of mixes of a whole bunch of stuff that create things.

Like humans are complicated AF.
