ARE gay rights civil rights? Of course they are. "Civil rights" are positive legal prerogatives--the right to equal treatment before the law. These are rights shared by all--there is no one in the United States who does not--or should not--share in these rights.
Gay and lesbian rights are not "special rights" in any way. It isn't "special" to be free from discrimination--it is an ordinary, universal entitlement of citizenship. The right not to be discriminated against is a commonplace claim we all expect to enjoy under our laws and our founding document, the Constitution. That many had to struggle to gain these rights makes them precious--it does not make them special, and it does not reserve them only for me or restrict them from others.
When others gain these rights, my rights are not reduced in any way. Luckily, "civil rights" are a win/win game; the more civil rights are won by others, the stronger the army defending my rights becomes. My rights are not diluted when my neighbor enjoys protection from the law--he becomes my ally in defending the rights we share
