I’d argue that you cannot. Social media inherently needs to hold your attention for as long as possible, and will do that through controversy, misleading and false information, and an attempt to manipulate. It’s part and parcel of the product, and extremely harmful to society as a whole.
I think you're misunderstanding the argument altogether, honestly.
The argument isn't whether social media is toxic but whether users can do some work themselves to filter out as much of the toxicity as possible and still benefit from using it.
This thread is really just a circle; things in the right moderation aren't so unhealthy.
