You're speaking about accessibility of the safe space. It's easier to access a social media and use it as a safe space. But, it doesn't opposite with the fact that social live and social media are different.

Safe space was a thing before the event of social media. Social media helps people discovering their differences and accepting these. This is access to the information and not social live. I didn't write people have to avoid social media.

Before the wide spreading of the internet, people would move to a different town, will reach specific places for safe spaces. They were free or used networks and didn't rely on private companies like Meta. This is a huge difference.
