This really has nothing to do with "inclusiveness" and more about politics.
First, white people aren't banned from attending, there's just four specific activities:
-One for black women
-One for black people
-One for people of colour
-One for everyone
The """"""segregated"""""" places are held in private places while the other is held in a public space.
Furthermore the city of Paris is already funding places where some people based on gender aren't allowed to go in (a "maison des femmes" where women can go and be protected from abusive men). So championing inclusiveness isn't a proper way to condemn this when your funding places which ban people based on gender.
Let's add the fact that the LICRA and SOS Racisme are joke organisation for a lot of people and that this whole thing was started by the french equivalent of Breitbart and 4chan and I'll let you fill in the rest.
(I really like this post)
Yeah, at its heart, it's definitely people playing politics, and Hidalgo and these organizations playing to the right/far-right's tune. It was started by FN, but on these issues, there's virtually no difference between FN and half of the mainstream right. These guys were concern trolled and they fell for it. I don't think the festival's messaging was great, but as you said, these kinds of private, exclusive spaces definitely exist and create no outrage. The "could I walk in there?" test is a trap.
On a broader note, I think we do have an approach to these privileged/unprivileged issues that generally runs counter to the Anglo-Saxon approach. There's this very theoretical, universalist undercurrent that demands a perfect reciprocity for every principle (i.e. "don't fight discrimation with discrimination") and it's deeply ingrained within our education and thought processes, including if you're a progressive who grew up in a progressive household.
This approach tends to be unpractical, and is often a just principle with unjust results.
Meanwhile, there's a shitload of issues where we (privileged French people) collectively sacrifice principles to practicality and are hypocritical. Typically, we will bypass educational districts to make sure our kids don't go to school with the poor, brown kids from the neighboring district, making sure they don't mix.
We have de facto segregated housing, with rich towns and districts going out of their way to either avoid affordable housing units entirely, or dumping them all in one place (i.e. dump all the poor people together). Some towns would rather pay fines for not meeting affordable requirements, this says something.
I mean, there's a lot of great people and inclusive places, but we vastly overestimate how open and tolerant we are.
