I use trans as an adjective to describe the type of man I am, and cis to describe non trans people.
I'm going to copy/paste the reason why I don't like ftm/mtf
Problematic: MtF, FtM, transgenders, a
transgender, a transsexual, a trans
Preferred: trans people, transgender
people, trans women, trans men,
women, men
The acronyms MtF and FtM are still
very common, but their use is being
phased out because they make it sound
like someone is stuck in transition
forever and define trans people by their
birth assignments. Trans and its
variations are adjectives, not nouns.
Using them as nouns strips trans
people of their identities and objectifies
them. You wouldn't say "Erin is an MtF,"
you'd say "Erin is a woman."
and more on the space...
Problematic: transwoman, transman,
trans-woman, trans-man
Preferred: trans woman, trans man
The one-word "transwoman" or
hyphenated "trans -woman" imply that
trans women are a "third gender,"
distinct from woman. By including the
space, trans is just an adjective
modifying a particular type of woman,
just like Asian woman or young woman
or liberal woman. While some self-
identify with these terms, they are not
generally accepted.
and on cis...
Problematic: real, bio, genetic, natural,
born
Preferred: cis
Trans people are not fake, artificial, or
unnatural. Their genetics have the same
effect on them that cis people' s do, and
they're born to be who they are just as
much as cis people are. Cis is also
preferable to "non-trans, " which would
unfairly create a labeled group and an
unlabeled one.
