I think we have a lot of laws we don't need. Sometimes it's simple. I read from time to time about efforts in this state or that to make same-sex marriage more difficult, and I wonder why. If two men or two women want to marry, why shouldn't they? Nothing in what they're doing compels anyone else to do the same thing.
And if the same-sex couple adopt a child, who knows whether it will have a happy life any more than any other kid will.
Restrictions on abortion? That's a harder call because there's another life--the fetus'--involved. But it still seems to me a woman has the right to decide what to do with her body.
Saluting a flag? Surely it's up to you, not someone else, what flag, if any, you salute.
And I'll bet you can think of some more examples. My point is simply that we don't need a law for everything. There are plenty of questions grownups can decide for themselves.
