Oh I got the point, all right.
Dean came out in support of civil unions primarily because "The overwhelming evidence is that there is very significant, substantial genetic component to it,". That is a quote from your own post.
He later added, "My view of Christianity . . . is that the hallmark of being a Christian is to reach out to people who have been left behind,".
Fact is, the civil unions bill has been under unrelenting fire from the Religious Right for years. Almost everyone who opposes it does so for religious reasons, or is closely allied with right wing religious groups. So Dean made a statement which evened it up.
Dean or the liberals didn't bring up the religious aspect on this issue. The conservatives not only brought it up, they harp on it and harp on it year after year. Apparently conservatives have no problem with somebody invoking religion to support a right wing theme, but citing any religious support for a liberal theme is strictly forbidden.
PS: And now, apparently, even the venerable Congregationalists, one of the oldest and most respected churches in American history, are due for snide attacks because Howard Dean is one of their members. Where does the need for the Right to attack ever end?
