I can understand wanting to provide a safe spot for those who have been victims of rape, or have PTSD, and etc, but if it's just because someone heard an opinion they didn't like, I don't see the need for "safe spaces". Besides, the Internet is a thing. You can easily navigate the internet to build a safe space for yourself.
Heck, you can make Atlas into your own "safe space" if you put everyone on ignore.
I am really tempted to do that for a day.
There is a limit (50?) somewhere. I have never hit it myself, but some posters have. Oldies complained about not being able to put more people on ignore.
