White male shaming: Now moving on to grander things like selfless community pursuits such as contributing to open source (just an observation, not commentary)
Suggesting that white males are more selfless is a bullshit answer. Maybe they (we) are the only ones who have the right combination of being educated and having enough free time? Maybe this has something to do with gender stereotypes? Or gender roles and woman usually having much more additional non work related responsibilities? I don't know. But it's worth asking.
I think parent was saying white male people shouldn't be shamed for participating in a "selfless" activity even if they're over-represented in that activity. I don't think parent was implying white-male people are over-represented in that activity because they're more selfless.
