We always have the freedom to make wrong choices. But there are consequences for all of our choices, good and bad. I have the freedom to rob a bank. That is my free will to make that decision. But seeing as that is against the law, there will be consequences.
Since we do not live in a vacuume, very rarely will 'wrong choices' not affect someone else. For 20 years I smoked. Not around the family. Never in the house. Only at work in my truck, alone. I have the right to smoke in America. It is legal to smoke in America. I was responsible by only smoking when alone, and never in a public place. Did this 'choice' affect anyone?
I had freedom to choose that path. It really had nothing to do whether smoking was legal or not. I assumed it would not hurt anybody. If I where to tell you that the Docs only gave 2 more years at most to live with this lung cancer I have, would you think anyone other than myself has been affected? Ask my wife if she's affected. What about my 12 & 6 yr old?
This law of 201 years was passed for a reason. The wise men of old, after fighting for freedom and liberty, decided that two consenting adults should not lawfully be allowed to live together without being married. Is there anything in their wise minds that could have fortold what the consequences of living together outside of marriage may result in? Could they see the harm to others by choosing this avenue of behavior?
As far as the slave issue, I won't say the Constitution is infallible. But there was not a law or amendment in the Constitution stating that the owning of Black slaves as property was righteous and true. When they realized they needed a law or amendent stating that it was wrong to own Black slaves as property, they put one in it.
Such is the case with this 201 year old law. At some point, legislators realized a need for it by looking at the results of not having it. Hopefully, the higher courts will agree with these wise old men.
If not, how long will it be before a group of people don't see the relevance of the 13th Amendent, and use an activist group of people to get it tossed out?
Let's hope for at least 201 more years.
