Well let's see... marriage.. that's a tough question. If you defined marriage as a scared union under the watchful eyes of the church. I would have to say no. Just as homosexual marriage should be allowed in a church because it is against everything that the Church holds as values.. why should they accept that.. should they accept murder as well? NO NO NO.. but if you base marriage as a union of two people in the eyes of the state.. hmm interesting.. for tax purposes? or to just snub the state into accepting the practice... Hmmm I'd have to say the state can view a union by law any way they wish.. if the people in that state vote to changes the rules of marriage well so be it(i'd be really scared for this country if incest got 50% of the vote). Regardless that puts the state in a position of basically facing the will of the people and it should be that way.
if the people in that state vote to changes the rules of marriage well so be it So morality by vote hmm? We dont need to worry about the 50% that vote for the incest marriage, it all starts with the perversion enablers like you Mr. Slippery Slope, the rest happens over time. Consensual pedophilia, if affirmed by the state, would be next.
