I don't accept civil unions as a "compromise" because I don't believe they truly are one. Just because something is in the middle of two positions, doesn't make it a fair solution. (and no....it's not really the middle, it's obviously closer to gay marriage than not)
Ultimately, although civil unions are preferable to what most states have now...full gay marriage rights are the morally correct way.
When we all have civil unions, eventually Keller will open up his mind to gay marriage.
I support gay marriage. but I really do not get the passion people have to that issue.
