social media is only bad if you don't curate what you're looking at. most the platforms these days have features to block posts containing certain words or hashtags.
i've made a lot of great friends using social media over the years both where i live and in other countries.
Most social media is actively against that, feeding you recommendations to keep you on the platform.
It's bad because you can't curate it. For example on fb there is no way to disable reels.
I only use group pages on FB, so there are no reels.
