That's a really interesting question! Thanks for your feedback :) I'll do my best to answer — hopefully I'm interpreting your question the right way. While allies willing to offer a listening ear and shoulder for support are generally appreciated, there's something unique about sharing experiences and providing comfort within a group of people who know and have lived the life of someone with that specific identifier. That's not to say, of course, that everyone in a safe space must have all of the exact same identifiers; it simply means that a safe space for, say, LGBTQ+ people will be filled with those who identify as such. As allies, there is a time and place for us to step up and lend our support, but we should also be cognizant of when our presence isn't needed or wanted. I would think that the situation varies by each specific safe space and what expectations are set up, but in my own research and experience, this is what I've found to be true.
