Oh, I agree. It's not automatically a good place to work for those who aren't directly discriminated against, and it can be really frustrating to watch.
Still, it's a better experience for the person who is blind to it, than the person who sees it but can't fix it, than the person more directly discriminated against.
In today's tech world it is possible for an organization - especially a small one - to remain discriminatory and not fall apart, while the discriminators themselves remain relatively blind to it.
It will never be as good an organization as it would be otherwise, though.
