Worse, denying same sex parents marriage doesn't magically make them opposite sex parents. It only guarentees that these children never have married parents. Which hurts children by the tens of thousands.
That's not what these amicus briefs said:
‘Quartet of Truth’: Adult children of gay parents testify against same-sex ‘marriage’ at 5th Circuit
Not one of these children said that they benefited because there parents weren't married. Nor that they were hurt because there parents were married. Nor that marriage would have made their same sex parents into opposite sex parents.
You're railing against gay *parenthood*. Which begs the question you refuse to answer: do you call for children to be taken from their same sex parent?
And of course, there were many, many more amicus briefs filed in favor of same sex parenthood with dozens of accounts from the children of same sex parents:
‘BRIEF OF AMICI CURIAE, FAMILY EQUALITY COUNCIL
With other briefs filed in other same sex marriage cases filed that add their voices to the choir, with children of same sex parents coming out in support of marriage for same sex couples:
Amici Curiae from Friend and Family of Lesbians and Gays
With other briefs filed for the Windsor case with testimony from even more children:
Testimony of children of same sex parents in support of same sex marriage
With child after child of same sex parents coming out in support of their parents having the right to marry:
The Outspoken Generation - Family Equality Council
With even constitutional scholars specializing in the constitutional rights of children recognizing same sex marriage as benefiting their children:
Brief of Amici Curiae Scholars of the Constitutional Rights of Children in support of their petitioners
Which you should pay special attention to as it cited directly in the Obergefell decision.
Amici are scholars of family law and the law of equal protection. Amici submit this brief to: (1) draw attention to this Court’s precedent unequivocally establishing that states may not punish children based on matters beyond their control and (2) demonstrate
that state marriage bans inevitably and necessarily perform exactly this impermissible function because they deprive children of same-sex couples legal, economic and social benefits associated with the institution of marriage.

And the Supreme Court apparently found the accounts of these children and constitutional scholars compelling. As they recognized the harm that denying marriage to same sex parents causes their children:
Windsor v. US said:
"And it humiliates tens of thousands of children now being raised by same-sex couples. The law in question makes it even more difficult for the children to understand the integrity and closeness of their own family and its concord with other families in their community
and in their daily lives.....
.....DOMA also brings financial harm to children of same sex couples. It raises the cost of health care for families by taxing health benefits provided by employers to their workers’ same-sex spouses. And it denies or reduces benefits allowed to families upon the loss of a spouse and parent, benefits that are an integral part of family security. "
And again in Obergefell, paying special note one of their sources, the Scholars of the Constitutional Rights of Children.
Obergefell v. Hodges said:
By giving recognition and legal structure to their parents’ relationship, marriage allows children “to understand the integrity and closeness of their own family and its concord with other families in their community and in their daily lives.” Marriage also affords the permanency and stability important to children’s best interests. See Brief for Scholars of the Constitutional Rights of Children as Amici Curiae 22–27.
That you personally disagree with the Supreme Courts conclusions is legally irrelevant. Especially when you're citing your imagination as the law, while ignoring the actual law.
