“Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.”
After World War II, when a publisher wanted to issue an English translation of Mein Kampf, there was an uproar. Thanks to the First Amendment, it was given the go ahead. Similarly, after the Oklahoma City bombing, when it was discovered that Timothy McVeigh was inspired by the book The Turner Diaries, the book was mass produced. Once again, thanks to the First Amendment.
The importance of those 45 words is not in protecting the simple and unoffensive. Instead, they are meant to protect the words of those who inspire great hatred. As much as it pains me to write this, the First Amendment is designed for such people Westboro Baptist Church. It gives them the right to assemble, so long as they so in a peaceable manner. It certainly gives them the right to spill their vile words.
If no one ever spoke or wrote in an offensive manner, perhaps there would be no need for such a provision. That, however, is not the case. We do need it.
To me, this is the core upon which our country is established. It is why we exist. Without this, nothing else matters.
