What?

Yes, the purpose of "free speech" is to allow the spread of ideas. The purpose of any particular piece of speech (a book, a pamphlet, a poster, a sign, a rally, a concert, anything) is to spread an idea. The idea in that particular piece of speech.

Do you want to preserve free speech but ban speech that tries to spread an idea? Your comment would be banned because you're trying to spread that idea.

Commercial speech is a legal term for speech that promotes commerce [1].
