Should the government actively encourage certain behaviors such as traditional marriage, that are deemed "moral" by the majority of Americans?

No.

No. If the behaviors are deemed “moral,” then let the majority of Americans decide to do them for themselves.

No. It is impossible to legislate morality.

Well, the entirety of criminal law is traceable back to moral codes. I think that anyone who’s completed Philosophy 101 can tell you that “moral” is not a word with one definition. But reading more into your question, it seems to be asking, “if the majority of the country gives something a thumbs up or down, should that become law?”

To which I would heartily respond, fuck no.

With the current divorce rate, spousal abuse, cheating,etc., I’m not so sure traditional marriages are ‘moral’.

Absolutely not. Women didn’t used to be able to vote and there were slaves, which were deemed acceptable by the majority of Americans. ‘Nuff said.

Marriage is moral?

@syz: All your links reference divorce? Are you saying that divorce is immoral or marriage is immoral? Why do you think that either are immoral?

Nope.

@critter I’m saying that there is nothing inherently “moral” about marriage, merely that it is a socially acceptable construct that’s image has tarnished.

The government has no business telling its citizens how to live their lives.

I agree with @dynamicduo, with the qualification of “as long as it does not interfere with another person’s self-determination.”

@syz: gotcha! I would agree.
