I read through about 10 pages of this...and not one person has mentioned this:

There are different RACES in this game...is it taboo to mix within completely different species?!

I mean is a Rog going to be able to marry a Miq or Taru(lol)?
If so, then why is same sex even on the table...
seems like you should be able to marry whoever the F you want, or even make a pledge of celibacy/be single.

S.E.: Just put it in from the beginning and never mention it again. Not many will care, and adding it later due to political pressure or whatever will have made you seem outdated, or weak. If someone asks why you allow it, ask them if they oppose Human and Rog unions, and make no more comments.
