Going a bit further: not being able to apply consequences to speech is itself curtailing your speech, so you literally can't have one without the other!
No, not really.
Your right to speech isn't infringed if someone does not share your personal opinion. You're always able to express your mind about how profoundly you disagree or how wrong you feel everyone around you is.
What you cannot do is go around strong-arming people to shut up or stop expressing ideas you don't share. That is not a way to protect your right to free speech. That's just fascism 101.
I can't stop others from doing business with you, though I could convince them
Not really.
I have no right to show you the door at the local library or cinema or car wash or local cafe, or at your own home. At most, that lies in the right to property,which only applies to things I personally own. Consequently, in a free and open society "showing someone the door" is a right that's only at the reach of private property owners or people mandated by said owners to manage some aspect of it.
Even then, that right to "show someone the door" because you don't like their opinions is not all powerful and is limited in some jurisdictions which also recognize the right to equality and non-discrimination. Think about it for a second: how can you have a free and open society if you do not have tolerance?
