Cute.
Alas, "homosexual" — like "polyamory", "microgravity", "electroconduction", and "mammogram" — is a Greek-Latin compound.
("Homophile" was current once, but no longer; "polyphilia" is sometimes reported, "multiamory" not so much; "microbaricity" would imply vacuum rather than freefall; "anbaroconduction" unreported outside certain fantasy universes; and a "mammoscript" sounds like the upstairs equivalent of a Vagina Monologue.)
A fun article by Alan Jacobs. Check out the paper he cites, if anyone finds an non-paywalled version, I'll edit in the link here. HT for the link to Michael Bloom.
I really do need to find more written by this author. But while I certainly do very much share this sentiment I have a hard time figuring out how common it is. After all people don't look good saying they "don't like meeting new people".
