I see the argument against the legalization of homosexual marriage from religious conservatives but I have to ask, just looking at homosexuality alone, is there a legitimate argument regarding homosexuality as being unethical?
There is no such thing as ‘homosexual marriage,’ there is only marriage, as either defined by the state or by a given religious dogma.
Homosexuals merely seek access to that same secular marriage law opposite-sex couples have access to, as defined and codified by the state; nothing more, nothing less.
As private entities, of course, religious institutions cannot be compelled to accommodate same-sex couples, as 14th Amendment jurisprudence applies only to the public sector.
Otherwise, why would homosexuality be any more or less ‘unethical’ than heterosexuality?
