I'm in the San Antonio area, and I'm inclined to echo the sentiment that acceptance will vary depending on where you are and who you deal with. If you visit a Unitarian Universalist church (at least in SA), you shouldn't have a problem. With catholics (on a group/individual basis, outside the church), well, your mileage varies, as they cover about the entire ideological spectrum. The four big metro areas are probably your best hope (Dallas/FW, Houston, San Antonio, and Austin, each with their own idiosyncrasies).
