I know trek is fiction however trek has always reflected our society and this society we live in has proven time and time again that it is best for a child to be raised in a household where the father and mother are either married or are in some sort of commitment (domestic partnership) with one another.
Of course there are circumstances (death of a parent , illegitimacy, domestic violence or divorce) when most children would not be able to experience the traditional family structure.
However , when an opportunity is given for a child to have a mother and father as a married or stable couple, I say no child should be denied that.
For the past 3 weeks since the Travyon Martin case , race and the family unit has been a hot topic in America . 73% of African American (AA) kids are born out of wedlock with absent fathers, this scenarios has contributed to why a lot of African American men go down the thug life which only leads to imprisonment, drugs and death.
Of course this is not just for AA, Its for young men in general. A lot of men (not all) with absent fathers tend do worse in life.
So I say Trek should keep the traditional family unit structure.
Relating my personal opinions to the Trek couples, Carol is now on the ship, if David is born in this timeline, Kirk would definitely be there with her to raise him. Chris Pine's Kirk seems to get more mature with every film so I don't see him not be there for his son.
As for Spock/Uhura, Vulcans have always been traditional. In the comics Spock did defined their relationship as a courtship (you an get more traditional than that). So I don't think they would jump into anything.
which to me, is the way it should be in the real world.
Someone commented on JJ and his view on marriage. JJ is married with 3 kids and his leading female character , Sydney Bristow from Alias. got married and had two kids with her husband by the time the last episode aired
So I don't see JJ straying away from that ideology.
Forgive me for ranting but I am just so sick of how most young people of this generation have come to embrace the baby mama and baby daddy nonsense.
