All along, the homosexual lobby has been comparing the plight of the American homosexuals to that of the American Civil Right Movement. They believe it is completely synonomous, and thus individuals and businesses making the decision to simply not provide support or services to a gay wedding is paramount to segregation.
Keep in mind that the homosexual population is 1-4% of the population. We are redefining an institution whose soul purpose is to protect children and give legal obligation to men and women who have children--all on the demands of 1-4% of the population. It is not enough to give civil unions, allowing homosexual couples the same benefits as a marriage, they demand we redefine the entire definition of the word.
The left has been waging a war, literally, against the institution of marriage since the 60's. Little by litte, court decision after court decision, inch by inch--chipping away at the foundations of marriage. Having a child out of wedlock had legal consequences once upon a time. A man had no right to a child outside of marriage, and a woman had no right to that man's finances. That court decision opened the flood gates, leading to adoption numbers to drop drastically from the 60's to present day.
