This is not in any way what a safe space is - stop promoting this completely inaccurate meme to further your own personal viewpoint. It has absolutely nothing to do with being unprepared for "real-life" or some other such nonsense. In fact I'm so confused why you would even bring up such a non-related topic, you must have quite the talent for shifting conversations to your favor.
"In educational institutions, safe space (or safe-space), safer space, and positive space are terms that, as originally intended, were used to indicate that a teacher, educational institution, or student body did not tolerate anti-LGBT violence, harassment or hate speech, thereby creating a safe place for all LGBT students."

(Just to be clear, I have no intention of derailing this thread into the merits of safe spaces - this probably ain't the space. I just felt it was necessary to call out.)
But in case you are wondering about the downvotes, it is because you have done the opposite of convince anyone. The tone of your comment seems like over-reaction and is just going to confirm the priors of anyone who doesn't see things your way.
Now one is free to have the opinion that safe spaces stifle discussion, or prevent ideas from being addressed or some other such things - those are all opinions and all views that can have their nuances. But safe spaces were never created to prolong some sense of childhood comfort or safety - like I said, that idea is just a popular meme of the alt-right.
