Your friends sound like the real red flag here. I am 30 and have no social media either. I consciously quit facebook back in the day and have never picked up something new since then, except reddit (whatsapp aint no social media either).

I think its sad how much your friends seem to already be consumed by their social media addiction or whatever that they can't even imagine a life without it or anyone else living without it.

TBH it would only be a PLUS for me if the woman I date has no social media. It would just show me that our opinions on the matter are aligned, because social media is like poison to the brain.
