You have no understanding of the difference between "equal application" and "equal protection". I could make a law that argues that people are only allowed to marry their own race. That law would be considered "equal application" since only whites could marry whites and blacks could marry blacks. However, that law would not be equal protection since the government is arbitrarily using race to apply restrictions to civil rights. Same sex marriage bans are equal application but are not equal protection since the government is arbitrarily using sex to apply restrictions to civil rights.
Nice try though. Pretending that "equal application of the law" is the same as "equal protection of the law" is the same strategy that was used by segregationists for decades. You have certainly fallen quite a bit if that is the playbook you have decided to borrow from in this debate.
