So like if I think not using master/slave is not only important morally, but also important for recruiting, is suggesting we remove it for business reasons a political discussion? Hmm.
I don't believe it's not allowed to be discussion though, just not permitted on the official company basecamp account. Perhaps the implication is that listening to your politics should be optional for other people working at basecamp.
This can't possibly be true as stated. Even if it's a metaphor, it doesn't add anything over leader/follower or, say, playwright/actor.
Plus it sounds like a sex thing.
