No, it probably didn't have any immediate impact on anyone because it didn't change existing law. It did set the stage for a lot of people to lose partner benefits, which WILL negatively impact their lives.
And it did more than define marriage. It closed the door on the State being able to provide legal recognition of civil unions or domestic partnerships. Before Amendment One, if the legislature saw fit they could have passed a law. Now when that day comes the Constitution will have to be changed again.
The MOST negative, most UN-American thing about Amendment One is that the rights of a minority group were put up for a popular vote, and the majority voted to say that rights cannot be granted to that group.
It would be like having a vote to decide if freedom of religion should only apply to Christians.
