If you don't like social media, why would you pretend to like social media to attract someone else who REALLY REALLY cares about social media? It's bound to fail.
It's not that these people actively care about social media or anything, it's just a regular part of life. I'm like OP here in the sense that I don't have any active social media attached to my name but I have some token pseudonymous social media accounts for exactly this reason. Being this obstinate about it is legitimately a huge red flag, and imo indicates that you've given up even more control of your life to social media, rather than understanding how to use it as a tool for a set of narrowly defined tasks.
