…it is special rights for gays.
Currently everybody already has the same rights with regard to marriage. You, homosexuals, heterosexuals, and me are all legally allowed to marry any person of the opposite sex of our choice who is distant from us in terms of kinship and who is not already married. Homosexuals have that very same right.
In other words, homosexuals as citizens of the United States have the same rights as I do. If a homosexual man wanted to marry a female who he is not related to, he could do so just as easily as I can. Homosexuals, as a group, are treated equally with regard to marriage as any other group.
“But gays are not allowed to marry the person they love”, you say. But that is the case with everybody. If I, as a male citizen of the United States fell in love with my sister, I would not be allowed to marry her. If I, as a male citizen of the United States fell in love with multiple women, I would be restricted to only marrying one. And just like gays, if I, as a citizen of the United States fell in love with another man, I too would be restricted in marrying him. In other words, gays, as citizens of the United States, have the same rights, and the same limitations, as everyone else.
Where the special rights come in is in the fact that gays want the exception to be given to them and only them. They want marriage to be tweaked in their favor, and to create special circumstances for them. What about other unions that also desire to be included in the marriage definition? What about people who fall in love with their siblings, should they be allowed to marry also? What about polygamists, should we now include marriage to include multiple wives? What about multiple husbands? Do these other groups not get ‘equal rights’ too? No, of course not, only gays get them, and not these other groups.
So what gays want are not equal rights, they want special rights.
