It's not clear to me what it means by "moral"... does it mean aligned with the mainstream morality of our society, or does it mean what I believe is good according to my personal morality? There are a bunch of cases where these two differ (for me), just think of the Snowden and Silkroad cases, or attitudes towards marriage or promiscuity, or towards religion.
