"Thank you. I also agree with the points you bring up, except one: "I think it is extremely unlikely that anyone would ever seriously make these suggestions because both males and white people are already in the majority." "
Hmm? Either you are misunderstanding me or I am misunderstanding you - I thought we were talking about men and women's participation in FOSS?
If you really think males are in the minority, I would encourage you to go to a conference :-) I went to LinuxCon Europe last year and from what I could see the number of (predominantly) white males outnumbered the females (either white or not) by quite a lot. From personal observation, I would say a less than 10 percent (female) estimate would be roughly right here.
No doubt this would vary according to the country the conference was in and what its focus was though.
