It only "has to be acknowledged" if it's true. The "evidence" for either of those, but especially social media (as if that were even a single well defined thing to begin with) is pretty damned shakey. Nobody "has to acknowledge" your personal prejudices.

You've convinced me that pornography is, in fact, beneficial to children. What was I thinking? Thank you for your reply.
