You definitely shouldn't be in a safe space when you're an adult (at least not in the verbal sense) ...

Sometimes bullying can make an individual stronger or it can lead them to the ultimate safe space, mental asylums or prisons ...

Kids are usually more naive and it's easier to get the wrong idea too so I'd be wary of encouraging bullying in this case or even bullying at all since it's not good in any shape or form ...

I was physically harassed in my high school days but I don't know if I've become a stronger person for it when I easily get triggered to even just the slightest intention physical assault to come back trying to aggravatingly beat up the other person and maybe even smash them into concrete surfaces or even hit them with blunt objects ...

Constant bullying just isn't healthy at all for anyone and especially physically speaking when laws reasonably exist to avoid such bloodshed which can lead to major discords in society ...

I have no qualms on being ideologically challenged though since I don't pity those who are weak in the mind when the rest of the world is far more merciless often times ...

We all have safe spaces. We invite only friends not enemies to our homes, because we wanna feel safe at home. In time of crisis we tend to rely on family, so family is sort of a safe space.

How is it about public spaces? Well, that depends on the definition of safe space. Do I want the public being free of crime and abuse? Sure. That doesn't qualify it for me as a safe space, but some people might see it that this is enough to call it safe space.
