I'm just wondering at the logic behind why they were giving a tax break to marrieds that they weren't giving to singles? Do you have any idea what it might be? The logic behind it is simple. Most married people have children. It has traditionaly been the husband, usually the primary income earner, who dies young. The idea is to help the surviving spouse support the children.
How many registered domestic partners (virtually all of them "gay") have children? Some, yes, but very few. The grief angle is just a tug at the heartstrings, Irrelevant.
I agree with you. I can see no reason to give a tax break to someone because they're having sex with someone else.
The idea was to foster natural families and encourage them to stay together.
It hasn't worked. Take away the tax break for everyone or give it to singles to. We can call it the "because you're alive and breathing" tax break.
That makes a little more sense than the "because you have sex with something" tax break.
