It's about an individual having the right to speak and an individual having the right to discern for himself what he hears. If social media is too wild west for a person, the person can opt out.
What you think others might not need to hear may offend my definition if what I think others need to hear. Hence, we should not censure lawful free speech. There are limits to free speech such as yelling fire in a crowded theater that come with criminal consequences. If you break those laws or limits, you get to enjoy those consequences.
