Thats not what I meant, sorry if it came off as otherwise.
Your original comment was:
Being on porn sites all day is healthier than being on social media all day.
Which is definitely false. Porn, occasionally and controllably, is fine! But constant - and regular - porn viewing is definetely harmful.
While both are addictive, porn is far more addictive, and it give short term dopamine spikes, which makes everything else seem less interesting or enjoyable, again, this is only regular watching.
