Are you trying to avoid discussing how pornography is harmful?
Do you prefer to avoid discussing the scope of harm caused by pornography?
It doesn’t how harmful pornography is, or you believe it to be.
It only matters if it is allowed to be expressed or not under the law. If it is not allowed, then liberals will look at the Bible for the sections that violate your desired law and expect the law to be enforced upon the Bible.
You’re as bad as the liberal is in your inability to foresee the consequences of what you want.
