My point is, is that most people don't think about it, hence they don't care unless it's brought up.
If it was spread all over the news that people couldn't play dominoes on Sundays people would care.
If that's your point, then I agree. People probably don't think or talk much about polygamy laws. That doesn't mean people don't care about them. It's just something that has been settled for a long time and doesn't come up too much.
If people in Alabama knew it was illegal to play dominoes on Sundays, they would probably repeal that law. (At least that's my guess.)
I doubt we can say the same about polygamy. Everyone already knows it's illegal and has been for a very long time, and there has been no real movement to make it legal.
