Please re-add...

I agree with the OP but maybe not for the same reasons. Simmers are all different and play in many different ways. They might want a "traditional" family set up in one play and in another have a completely different family dynamic. I support 100% people who want to have representation in whatever alternative lifestyle they can dream up, provided that lifestyle involves consenting adults (looking at you horrible glitch that made dads look at their teen child daughters, eww).   I also support those who want to keep it traditional for whatever reason they may have whether that be religious of for whatever other reasons. This is a sandbox game and the player gets to decide for themselves how they want to play. Freedom, inclusivity, and representation means add choices not remove them. I wouldn't support any removal of terms that people CHOOSE to define themselves and I don't support this either.  

If this is an issue of trying to make the pronouns  work then they need to give the player base a candid explanation of the removals because it sure does look a certain way and that way does feel discriminatory. I'm sure if this is the issue then the players would move into acceptance until the issue can be sorted.
