These are comments by jdlm11235 and Schala on the post “Spelling Queer with L, G, B, & T (and A, I, P…) Part 2“.
Trans man and trans woman are new-ish terms, but the trans community has spoken pretty clearly on them: a space is warranted.
The idea is that there are not men and transmen, there are just men, some of whom are trans, some of whom are cis.
Here’s a reference: http://transkitten.com/trans/transperson-vs-trans-person/
There should be a space here. We don’t have whitewoman or whiteman or blackwoman and blackman. Trans or transsexual or transgender is an adjective affixed to a noun. It is not itself a noun.
