So..... I really used to hate the term "safe space." It sounded like the term used for a person who can't accept that life isn't fair.
As of now, I personally believe everyone should have somewhere to go to if they feel the need to just be alone with their thoughts for a bit and cool off. And even I'll admit.... Muppet central is a bit of a "safe space" for me (it's the only place I feel comfortable talking about politics on without getting jumped on by different parties; I mean, most, if not all, of us on here pretty much hate Trump which feels nice) and it's also a place I can vent about frustrations on (the rant thread, though I also use discord as well).
However, I also feel if you are being harrased, take some time to cool off in an area where you can be alone for awhile, but by all means, stand up for yourself, too. Don't bottle it up at the end of the day.
