Sorry khasim, you seem like a reasonable fellow, but you've posted this so many times as if it is somehow the nail in the coffin of the argument that I think it deserves a response. Flatly, your statistics are complete bullshit.
First of all, the percentage of females in the FOSS community is completely irrelevant. If you get a group of dudes together in a room to talk shit about women, the fact that the percentage of women in the group is 0.00000% has no bearing on whether or not the group has sexist tendencies. The amount of sexism you are "allowed" in a group is not somehow proportional to the percentage of women in that group. I don't know what else to say about it than to reiterate that it is a completely irrelevant point.
The second part of your point is better - namely, you say that only 0.1% (totally made up number, but whatever) of the comments are sexist, and that's pretty good. I agree, if you're right that 0.1% of all FOSS related commentary is sexist, that is really pretty good, and while it's probably impossible to get the numbers to back it up, I'd say it's better than the population at large. However, this isn't a victory for the FOSS community, it's a defeat for the population at large. Being less bad than average does not make you good. We should strive for 0%, we should strive for 100% acceptance of all the various backgrounds of the members of our community. 99.9% is good, but it's not *that* good.
That's the REAL problem we'd like to solve. We'd like to do much better.
