Any subject important enough in any public forum is potentially going to have wrong opinions that are going to cause harm. While some people could be wrong, and could cause harm, the state itself being wrong is far more dangerous, especially with no dissident voices there to correct its course.

Edit: I see you're getting downvoted for simply stating your honest opinion. But as a matter of principle I'm going to upvote you.
