Second, if this person is actually your friend, and not, I don't know, some kind of minion, you'll respect that they have their own brain and their own moral compass and they're capable of making their own judgements. Maybe you'll even be comforted by the fact that you'll occasionally disagree, as those events validate the notion that we have free will and are not simply deterministically arriving at the same conclusions from the same stimuli.
We're dragging this out a bit now. Obviously, I don't believe that you'd cut off your friend because they made a career decision you didn't approve of.
I'll be in SFBA the week of the 18th. Happy to buy you a beer.
