I was thinking this morning about how an Erastilan might be trans-affirming (because Erastil is often portrayed as the conservative-stick-in-the-mud god) and came up with this line:
“’At’s ol’ Hulda the Milkmaid. Settled on the hillside twen’y years ago when her name was Hull. Had a sword wit' 'er broader'n a man's hand. She pulls four buckets o’ milk ever' mornin’ an' she’s caught more calves than any o’ us can count. We like Hulda, and iffen you’re meanin’ to start somethin’ with her ‘cos you think she looks funny, you’ve gotta go through us first.” - Verris Loran, High Priest of Erastil
Well, if a culture has been trans-affirming long enough, then trans affirmation *is* conservative. I haven't really seen any indication that trans-affirmation is something new and unusual on Golarion, and given that there's a demigod who is often associated with trans folks (and has a long association with a major city), it seems a long-settled general thing, so... if trans-affirmation is status quo, conservatives would seem to tend toward support.
