Sure and sure. I look forward to your response.
I generally remain pro-freedom-of-association. "Safe spaces" as it were created by communities of various types are fine by me. The problem comes in when it's not uniformly allowed. If a group of black people want to create a white-free space, more power to them. Just don't flip out if a group of white people want to do the same thing. Same thing goes for groups of men, women, LGBTQ+, religious affiliations, etc.
Just at the outset, I want to point out that none of what I'm going to say is to mean that the end of Jim Crow was a bad thing, quite the opposite. Not the prettiest opening statement, but I want to be clear on that. Now, on your so-called "pro-segregation" thing, there were in fact unintended consequences of integration which, naturally, negatively hurt the black community while giving the white community the feel-good of solving segregation and the related social ills without actually doing so. Wealth income inequality between white and black Americans has increase seven-fold since "integration," and that's not a coincidence. Already capital starved black communities already hit with the double whammy of legal segregation and white-flight from the cities following the Great Migration suffered another blow by losing their upper-middle class demographic to whites in the suburbs after integration. Black physicians, business owners, lawyers, and so on, left, causing banks and other means necessary to participate in the economy, the means to social mobility, such as jobs, or the potential to build credit in order to buy a car or receive student loans, or even the possibility to move away to somewhere more economically vibrant, to whither away. In many places, even the grocery stores left. The coffers of majority black school districts dried up thanks to our not accidental way of funding school districts, like local taxes, thus withering away another mean of social mobility. Black children lost first-person evidence of self-potential from people they know by name in their community. Black colleges and universities lost their best and brightest (and whites weren't suddenly filing into their spots), who were now able to go to the more prestigious historically white colleges and universities to put them into a position of also moving to the white suburbs. Comparative enrollment dropped and funding dried up as state dollars moved to historically white universities, who then expanded graduate programs, causing many HBCUs to shutter their own graduate programs. And mind you, this is all in the context of children of slaves whose labor fueled the industrial apparatus that sparked the emergence of the wealthiest country of all time, many of whom today continue to live effectively under the yolk of a terror state, just as their ancestors had. And so on.
I'll save you my "the US is one giant safe space for white people" comment because I don't want to get into that debate (I grew up poor white in the rust belt with a single mother moving nomadically from one bad situation to another, so, trust me, I know that poor whites suffer too), but even in these black safe spaces, white people are free to come in and are welcomed when their intentions are pure. I studied at a black safe space. I enrolled in courses that were safe spaces for women. I marched in a safe space for LGBTQ+ and enjoyed their company at their safe spaces in their homes, bars, and clubs. How did it work out when a "safe space for white men" marched in public and confronted people who weren't white men? And yes, that last point was just a rhetorical flourish.
