Your side is wrong. You’re not always the good guys, and sometimes you stand in the way of progress more than you aid it. The argument you think is so airtight is built on flawed assumptions. Your leader has a lot to learn.
Hard things to hear. But if we have a trusting relationship with someone who will say them to us, we are well situated. Of course we can hear the errors of our side enumerated by ideologues on the other side. We’ll brush those off as zealotry and ignorance. They don’t agree with us about anything. A friend, though, someone who knows us and cares about us and agrees with us most of the time? When she’s willing to say “You’re wrong,” we darn well better listen.
That’s a gift.
