I admit I don't understand the protesting against safe spaces. My university is probably one of the largest of my state and we have a safe space called the "wellness office". It gives out free tea, lip balm, hand sanitizer, and fruits. In the evenings it lets specific people from the LGBTQA+ spectrum come and talk about things. E.g. "Bisexual and pan sexualities" or "Queer men" or "LGBTQ People of color" would all have their own weekly schedule to meet.

I've actually been to a few to see what exactly is going on and what I found was that those meetings tended to talk about issues that are very specific to those groups and therefore there couldn't be much in the way of discussion for people not in those groups. It's not too dissimilar from a meetup of people who want to discuss specific algorithmic proofs in that it's a "safe space" for people in that field and in that education and the quality of conversation would be less productive for the people there if someone not in that field or education arrived and joined in with a bunch of confusion or lack of education about what algorithms are.

I really am confused because I've yet to encounter a "safe space" in which I felt that there was a plan to censor people or order people that they can't say certain things. Meetings hosted by the "safe space" at my university have come off to me as a space to intellectually discuss topics more or less pertaining to a demographic who would otherwise not have as productive a conversation if they had to explain what sexuality is. I've also experienced similar environments in editor's meetups in literature and research groups in STEM.

Could you provide me with a study or article regarding how the existence of an isolated space for the discussion of topics is wrong or bad? I don't mean to attack you or say that "safe spaces" are a good thing. I just don't see the difference between "safe spaces" for minorities differs from spaces of intellectual discussion in STEM.
