Luke T. said:What is the difference between a "civil union" and "marriage?" A tax break? What?
If you have a civil union and then break up, does one have to pay the other alimony? If you have a civil union, and one of them sleeps with someone else, is that grounds for adultery? Can they get the family rate on insurance?
What do people who are married get that civil unions don't get?
Well there are several. There are the issues of Social Security benefits, joint filing of income taxes, not being forced to testify against each other in a court of law, immigration rights of people who chose to marry someone from another country, inheritance rights, standing in child custody disputes, etc.
Homosexual couples can solve a variety of these differences with Civil Unions and Power of Attorney Agreements, but not all of them. As a purely practical matter, the cloak of Marriage that heterosexuals enjoy is vastly superior to the crazy patchwork of fig leaves that is the Civil Union.
There is also cost. A heterosexual couple that wants to marry just needs a justice of the peace and a marriage certificate. A homosexual couple looking for the same rights would need to spend hundreds or thousands of dollars in various legal fees and would never quite get there.
