At least I know everyone will read my post now.
Here are some questions I have.
1. What role, if any, should sex play in the government? Specifically, why should we get tax perks and certain privlidges just because of sexual unions?
it's social engineering by the government, and it should end
2. Should sexual relations imply obligations legally of any kind? Should a spouse be allowed, for example, to simply leave all of their estate to someone other than their sexual partner, or should the fact that two people had sex together for a specified time make them legally obligated to get a cut?
depends
3. Why buy a marriage license? Why should we pay?
you don't have to buy one if you don't want to
4. Should those who are monogomous be allowed to discriminate against those who are not by having special government privlidges over them?
see 1st response
5. What about asexual people? Shouldn't they have the same rights as those who are sexually active? For example, if two people live together and are the best of friends but don't have sex together, why is it they can't file jointly with taxes and provide the same privlidges those that have sex have?
they could marry and file jointly, nothing is stopping them unless they are of the same gender
