Younger generation opposed to same-sex marriage

A new Gallup poll says:

Some of the things which I thought especially interesting were the results which showed that younger people (18-29) support a Constitutional amendment banning gay marriage by a 56/39 margin (so much for the concept that gay marriage proponents just have to wait until the younger generation grows up), while the demographic with the least support for an amendment is people 50-64 (ie, the cream of the Baby Boomer generation), who only support such an amendment by a 51/45 margin.

The poll shows that opposition to same-sex marriage is increasing.
