This is a bit simplistic but:
I like the separation of church and state; and the separation of marriage as a valid man and woman institution. I want to keep The Girl Scouts separate from the Boy Scouts: the Brownies separate from the Cub Scouts, Campfire Girls separate from the hot-as-fire boys; Bluebird Girls from…
And to the point: the forever and always separation of gay civil unions from the term marriage.
And I am one of those mean old atheists.
