>Freedom of speech isn't freedom from consequences of that speech.

It is though, it's just that we as a society define which consequences you are free from as the speaker (ex. some legal consequences). The internet, and social media in particular, has profoundly changed how we think about the topic. In my opinion we'd be better off as a whole if we reevaluated our perspectives when presented with new information rather than avoiding discourse entirely in favour of dogma.

>and then not "punish" you for it? If you tell your wife she looks fat, she's probably not having sex with you that evening

This isn't a punitive action, it's a personal choice of your wife. AFAIK you are not entitled to sex with your wife whenever you so choose. A scenario in which a contract is terminated based on something said on social media (when there's no clause in the contract covering that particular thing) is fundamentally different, for example.
