Here and here it is in their own words. Their logic defies belief.
Strangely enough, there is a gay agenda. It reads something like:
gays want equal access to housing, transportation and employment
gays want the government out of the nations' bedrooms
gays want some legitimized form of "committed relationship" eg. marriage for tax, legal and emotional reasons
gays want their sexual orientation excluded as the sole supporting charge for "not in the best interests of the child" in custody cases
gays want the school system to stop teaching that homosexuality is a negative thing
gays want truthful portrayal in the media and the arts
Other gays may want other things, but the above is probably the core.
