Based upon your question you feel that even before the SC decision singles were already being discriminated against!
That would be true I suppose. Nothing changed for singles.
With or without same (sex marriage) single people were not entitled to receive the social security benefits of their "current mate".
I suspect one of the reasons why those benefits are for married people as opposed to singles is theory a married couple is (one family).
The governments of most countries have always (encouraged) marriage.
Personally speaking I have lived with six women over my lifetime and have been married twice. Most single people would not want their current girlfriend or boyfriend to automatically be entitled to their social security benefits. Most people have multiple girlfriends and boyfriends in a lifetime.
The only thing the SC decision did was allow same sex married couples to have the same federal benefits of heterosexual married couples.
Having said that there are many corporations that allow single people who cohabitate to have their significant other on their domestic partners insurance. Some may say that discriminates against those not cohabitating!
Single people also can list anyone on their 401k & IRAs as beneficiaries
Brad are you upset that same sex married couples have the same rights as heterosexual married couples? or Do you feel marriage licenses should be abolished altogether? Do you believe we should be allowed to will our social security to anyone? Did something change for (you) after the SC decision? or Have you always been against marital benefits for widows and widowers?
