"After all, "everyone knows" that blacks are inferior and only useful as slaves (they even want to be, deep down); "everyone knows" that women are too temperamental to vote sensibly; "everyone knows" that people of that religion over there eat babies and we should destroy them before they destroy us..."

This is simply not true at all these days, and I don't like that HN users would push a normal conversation into one where you imply your "opponent" is racist, sexist, or a religious bigot. Might as well have called me a Nazi or brought Hitler into the conversation.

And I don't believe you need Psychologists or a peer reviewed study to discern mobile platform usage, we have other ways to getting said metrics.
