one of the things i like about the constitution is that it's a living document. it's not finished and can be updated where needed/necessary. i see our country's laws in the same light.
the culture changes now and then, sometimes for the better (though not always). i think laws need to be fair for the majority and reflect what we believe at the time they're made.
i believe in the separation of church and state. so while i think our country should have some kind of moral guidance in creating laws, i don't think it's best to make all of those laws based on one set of Christian beliefs (hope that makes sense). for instance, while i don't support abortion outside of the life of the mother being at risk or in cases of rape or incest, i don't think this country can overturn roe v. wade at this point because it will cause more harm than good and people will go to extremes to still terminate an unwanted pregnancy just as they did pre-1973. nor would i try to remove all the guns in our society (too many to get rid of) but i'd work like hell to get rid of illegal guns and make sure people with mental health issues don't have access to them. and while i don't support gay marriage, it seemed inevitable that it would become legal throughout the country, especially as we saw one state after another make allowance for it. this was particularly an issue where we've seen a lot of change in society's acceptance of homosexuality, something that would not have even been considered in our grandparents' era. i think our national laws should always work for the greater good of society as a whole. smaller issues can be addressed by states or local legislatures.
i hope i'm answering your question. i think i might have rambled a bit.
