This happens because same-sex marriage is artificial and non-sustaining, therefore requires state interference to bring the bulk of the population around.
Marriage between men and women is a pre-political, naturally emerging social institution. Men and women come together to create children, independently of any government. The duty of caring for those children exists even without a government or any political order.The interference from the state comes in when people resist participating in the same-sex marriage experiment.
Marriage protects children as well as the interests of each parent in their common project of raising those children.
Because marriage is an organic part of civil society, it is robust enough to sustain itself, with minimal assistance from the state.
By contrast, same-sex "marriage" is completely a creation of the state.
Same-sex couples cannot have children. Someone must give them a child or at least half the genetic material to create a child. The state must detach the parental rights of the opposite-sex parent and then attach those rights to the second parent of the same-sex couple.
The state must create parentage for the same-sex couple. For the opposite-sex couple, the state merely recognizes parentage.
In her essay in The Meaning of Marriage: Family, State, Market, and MoralsNo wonder the left has a rainbow faction., Seana Sugrue argues that the state must coddle and protect same-sex "marriage" in ways that opposite-sex marriage does not require.
Precisely because same-sex unions are not the same as opposite-sex marriage, the state must intervene to make people believe (or at least make them act as if they believe) that the two types of unions are equivalent.
Public schools in California are soon going to be required to be "gay friendly." A doctor has been sued because she didn't want to perform an artificial insemination on a lesbian couple. A private school is in trouble for disciplining two female students for kissing. All in the name of supporting the rights of same-sex couples to "equality" with straight couples.
The fact that opposite- and same-sex couples are different in significant ways means that there will always be scope for the state to expand its reach into more and more private areas of more and more people's lives.
