Brian, this is an EXTREMELY poorly thought out argument.Same sex marriage is bad because it increases government corruption. See the actions of renegade justices of the peace in California and Pennsylvanian who illegally issued same sex marriage licenses for examples.
Your "argument" is that same sex marriage induces corruption in government officials who are tempted to violate the BAN on same sex marriage.
Remove the ban and _ALL_ that corruption vanishes.
Marriage Equality does not cause corruption, it CURES it.
