It seems odd to me. Paradox is a Swedish company, and Sweden is a fairly liberal country. Same-sex marriage was legalized in 2009, and even the Church of Sweden gave the go-ahead on performing same-sex marriages the same year.
The game logic around this is simple enough that changing two byes fixes it, so it's not a technical issue.
