Faith, it seems your position is that protecting the freedom of expression of people who make pornography is a bad thing. If I am wrong, disregard the rest of this message. If I am right, please continue.
What you are failing to understand is that your opinion or your religion's opinion of the content of speech is absolutely unimportant. People get to say what they like and the government doesn't get to stop them and you damn sure don't, both with good reason.
The very concept that makes American freedom noble is that it is for everyone, including pervy types who like watching extremely dirty movies. The thing that is wonderful about the bill of rights is that it doesn't (or shouldn't in it's original intent) just protect the popular thing.
You say that freedom of speech for those who are saying things or showing things that you don't like is ignoble? I say that one of the most ignoble acts an American can engage in is trying to limit the freedom of their countrymen because they don't like the way those freedoms are being used.
If negative effects of pornography made by adults for adults could be demonstrated, then it would be a different story. No such negative effects have ever been shown to the best of my knowledge, and if you think there are such effects, I invite you to start a thread and provide evidence.
In closing, I find it ironic that you would invoke the founding fathers in support of violating the right of free expression. I am nearly certain that, should they suddenly show up in the here and now, they would have much bigger concerns that some pictures of naked people, such as the violations of personal liberty engaged in by conservatives and driven by the religious right.
