If you believe that all parents are intelligent, informed, and put their children's well-being before everything, you are unfortunately wrong about society. Kids don't deserve to suffer just because they have neglectful parents.

Discord, on the other hand, should be at least somewhat responsible for the interactions of children (which they profit off of) on their platform.

And finally, you, a sentient adult with free will, can use another platform. Not your problem unless you want to make it yours, which is the response of choice on this thread.
