Don't like gay marriage ? Don't get one. My gay marriage doesn't change anything about your straight marriage . We're not altering the definition of marriage; we're expanding it. These new rights don't take away yours. So don't try to deny them to us. The startling rise in public approval for gay marriage depends on such simple appeals to intuition.

If they aren't harming anyone else, then who can deny their gay marriages equal protection under the law
