Johnny. Do libertarians understand that there is money to be had by the deviants. Government money. You cannot take the government out of marriage unless you change the tax code.
There is also the family and religion to be gotten rid of for the commies. Marriage and Judeo-Christian values are foundational to the success of our Constitutional Republic and the human race. Period.
Libertarians have not thought through morals carefully enough. We do not need to live in the Wild Wild West.
