Do you really want to get into what religious texts say to do to other people? You have some pretty twisted views on what a community is. Community doesn't give you cart blanche to discriminate against minorities. People shouldn't have to worry about losing their civil rights if they move from one area of the country to another. Save your "community rights" for issues that are localized to your community.
Sure, I'm happy to discuss theology and its effects. Communities share common values. Some of them, past and present, are explicitly based on religious values.
A couple examples: The Pilgrims, the Amish, the Catholic community of Londonderry (a city), Jewish boroughs.
Sometimes those values conflict quite radically with the mainstream. In the US where religious freedom was an important part of our founding - and enshrined in the Constitution - communities are free to set their own standards and expected lifestyles.
Marriage has very strong religious connotations. Many religious communities define marriage as being a union recognized by the church; they don't give a damn about what the gov'ment chooses to recognize.
I've heard a number of people (including liberals) suggest letting the religious keep their Marriage label and have the government use something else less specific to refer to all legal unions.
A couple possibilities put forth: garriage, sarriage, civil unions w/ all the rights previously reserved for marriage.
Marriage in the U.S. is recognized to be a power of the States to regulate.
I agree that DOMA is an overreach of federal power and should be overturned.
Separation of church and state is a nice idea but it has inherent limits.
People have to get their values from somewhere- religion, TV, now the Internet (I won't judge here).
...I'm trying to keep my focus somewhat narrow here and not bring the Declaration of Independence or the Pledge of Allegiance into this...
I personally don't see any solid reasoning preventing certain states from legalizing same-sex, polygamous unions, or unions with robots once they get advanced enough (there ya go nehalem256, I'm not an.. objectist?).
Now, banning the above mentioned unions raises different legal questions then acknowledging them in the first place.
lopri has been good about explaining the (laymen's I'm sure, IANAL) legal differences between legalizing polygamy and legalizing same-sex unions.
I'm still mulling over this.
