It's harder to convince people to all agree on the same, different from the norm, thing. If you've got 5 people in a car and you play ABBA in every road trip, then one day you suggest to change, the problem is not in being okay with "something else", but on agreeing what that other thing should be, set against the already known thing. That's why there's so much infighting in the left.
