Alas, this is the same argument that can be used against the 1st amendment and the political opposition: "Rejoicing in Kirk's death is immoral, therefore the 1st amendment doesn't apply, and let's abusively prosecute anyone we can tie to him in any way".
You said that morality must be above the laws. That means that one has priority over the other. aredox is arguing based on that, not confusing the two.
