Marriage should be about social recognition of status.
There is no social recognition of the 'specialness' of it anymore..for want of a better word.
Marriage is actually discouraged financially because tax breaks etc are no longer present and employers are not encouraged to support it by paying more for married workers or treating them any better with time off for family commitment etc.
The whole supporting social structure that used to exist is now almost extinct. A 'couple' no matter their age,gender,race etc are treated exactly the same as a married couple and given the same 'rights' (in other words no rights whatsoever) there is nothing special or unique about the partnership and therefore nothing special or unique about the products of the partnership, such as children, in the end you are all individuals who are treated exactly the same not only by the state but by each other through your social conditioning by the media and the state and the business environment.
By embracing 'equality' you have all embraced the right to be treated like shit equally.
What we all really wanted from 'equality' was to all be treated WELL not ignored. Of course that didn't happen, this whole idea of equality can only ever happen without any of the present control paradigm being present. Equality under authoritarianism is a joke, believed only by the most brainwashed of individuals.
I would simply say this...be careful what you wish for
Thats not to say either don't push for change or go all KOTG and wish the world back in to the dark ages, there's more to this than the dumb duality argumentum ad infinitum DIF stylee.
