You're right, I was wrong. Gasp, see how simple that is! Let me rephrase that to say "You can't say discrimination is wrong and then have an argument that supports it".
Luckily, that's not the argument. The argument, and the one supported by the courts for the past handful of decades, is "Discrimination in marriage is generally wrong, excepting for occasions in the obvious public interest". The question is whether or not there's significant enough harm in allowing homosexual marriage to justify the discrimination.
If someone wants to argue whether there's significant enough harm to justify not being allowed to marry their sister, infant child, cat or kitchen sink, that's a separate argument and has no place in this one except to confuse the issue.
