>For the articles to be "cherry-picked" they must be picked from ones that draw an opposite conclusion.
No, it means he picked articles that supported his viewpoint while ignoring the ones that didn't.
>There is a difference between proving something is possible and that something is True. Damore may have only demonstrated the first, but this is enough to refute the claim "There is sexism in tech because the gender ratio is not equal".
Damore demonstrated the first, and then used that to say that to completely discount any sexism in tech.
>This is why it is important that group differences are in part responsible - it puts a burden on Google et al to find the magnitude if that influence, rather than attribute all of it to sexism. In other words, you can't attribute anything to sexism (without proof) as soon as there are multiple possible influences/causes.
That exact statement could be used against Damore and his supporters.
EDIT: to add to this, Damore would've been completely justified if he had said this to open a dialogue, but he didn't. He should have said "There are multiple possibilities, let's not immediately jump to conclusions.", but he didn't. He took a handful of Wikipedia articles, twisted around what they said to fit his confirmation bias, then said "I'm right, you're wrong, deal with it." and then claimed that was the truth (his twitter handle is @fired4truth). He's very clearly a narcissist who can't handle that he could possibly be wrong.
