No, not proof by analogy, but explanation by analogy. As Scalzi says in his follow-up, providing proof of endemic sexism is about as necessary by now as providing evidence that gravity exists when tripping over one's shoelaces. The evidence by now is clear enough that to demand evidence in every discussion is a distraction tactic, and not actually useful. Finding evidence is, because of the sheer breadth and extent of the problem, as difficult as using your favorite search engine to look up income stats, harassment at the workplace, unfair hiring practices, etc., such that demanding evidence is pretty much asking someone else to do your work for them.
(I should note that Scalzi did link to another post with more facts, over at http://www.jimchines.com/2012/05/facts-are-cool/, if you still demand that someone else go search for things online for you.)
>[B]lack males receive [prison] sentences that are approximately 10% longer
I don't see how this is related to programming but yes it is correct. The effect is even larger for men/women, so that men recieve much longer sentences for the same thing than a woman would.
>The ratio of women’s and men’s median annual earnings was 77.0
This is mostly but not fully explained by choice of career. Women in the cities of US actually earn more than men.
I don't feel like responding to more, since they are unrelated to the topic at hand, proving discrimination in the workplace keeping women out of programming.
>providing proof of endemic sexism
It depends on what you define as sexism to be sure. If you define sexism as telling a woman she looks beautiful, or showing pretty women in your presentation, then yes of course you will find things like that.
>demand evidence in every discussion is a distraction tacti
Yeah, I guess it disctracts from reading poorly thought out analogies...
>income stats
Correlation does not prove causation.
>if you still demand that someone else go search for things online for you.
Wow are being really hostile. I have made no such demands. But if you try to "prove" your point by doing analogies or by linking to irrelevant stats like incarceration of black males, I will call you out.
