But although I've seen this sentiment quite a few times, there doesn't seem to be any consensus emerging about what else to call it, so 'homophobia' is still the word that's in use.

The terms queermisia and transmisia seem to be on the rise in the last five years or so, and have become the preferred terms in several communities I'm in. While there is a long way to go before a full switch, I'd certainly say it sees enough usage to count as an emerging consensus

(eg. Simmon's University discussing why they've switched to using the -misia suffix or Diversity Pride's -misia pledge though I'm personally more familiar with it from day-to-day casual useage on fedi/local queer orgs than I am with either of those organizations)
