So we will see all forms of marriage occur as you can't say no...Right? Brother and sister? Mother and son??? 3 wifes and two husbands??? You're a bigot if you say no as it goes against equal protection.
Ah Yes, the Incest Fallacy.
YOU do not have the Right To Impose YOUR Religious/Personal Morals or Values on others.
Your argument has no sound basis or use of logic in it.
The Right to Marry granted by the State, NOT by the Church.
YOUR a bigot if you believe YOU have the to decided for YOURSELF who can and/or cannot get married.
Marriage is Civil Right, NOT a Religious Right.
YOUR Religious Freedom does not trump the Equal Protection Clause.
YOUR Rights are just as equal as mine, or my younger sister who is a Lesbian.
YOU do not have the Right to decide who can and cannot be married.
As for incest, not exactly valid because as I recall incest was a primary means of procreation after Adam Eve, as their Sons and Daughters did procreate and that would have been through incest.
