Thank you, this is very useful! For several reasons:
I can share it with my white male techie friends, and they _might_ accept to read it because it’s from “one of them”, not some angry politicised feminist SJW hysterical woman :(
I can point you to some of those who are making baby-steps: what else can they do to help.
And I can use it to thank the ones who are already very helpful, to say “you are not alone” — there are more people who are aware of the problem, and searching for the solution.
