Well, we generally do not prohibit abusive speech.

What's prohibited is targeting people with speech who do not wish to participate (or who cannot, statutorily). Plenty of adults freely choose to engage in abusive relationships with one another and of course they are free to do so provided the other party is a willing participant.

The same is true of non-abusive language. Consider a simple romantic overture.

The lines are drawn around consent. Not content.
