Freedom of speech in private should mean free from consequences.
For example, if I say something controversial to my SO at home it shouldn't cause me to get fired because Alexa overheard and its recording leaked?
I suspect there is a lot of nuance to both sides here. Like if the president of the US tells racist jokes to their lover in private, then public consequences after a tell-all book may be in order. (By public I mean people may chose to vote them out.)
What if yer dog gets mad at you yelling at the television and bites you, that was a consequence, right? so ha! I've totally proven how silly you are for thinking that you should be able to make a statement to yourself about muhammed without actors in the middle east calling for your death!

When people talk about consequences for saying stupid things, this is exactly what they're talking about. Embarrassment for saying completely assinine things, not losing your ability to support yourself because you made a stupid joke when you were 14.
If you can't understand the difference between the two, that's a you problem.
You can bury your head in the sand and pretend this sort of damage isn't happening regularly, but the rest of us choose not to.
I raised my head up high and actively looked for the story by Googling "lost business daughter joke" and came up empty.
Stand on your own two feet.
Your argument forgets that it's also free speech to react to something objectionable. If the government forced me to do business with you without my consent, that would be compelled association, which is more similar to how Mao's government behaved in the 50s.
