Explain why? Both are communicated a message, while all pron is a bad message much ( I would argue most) social media promotes a very bad message for minors.
I challenge you to show how I made a false equivalence. Don’t just argue through assertion, defend your assertion.
“So you think laws against minors viewing pron are equally stupid? How progressive of you.”
You are making the equivalence that someone being against preventing someone from accessing twitter or facebook is equivalent to them supporting the same group acessing porn.
