That's very interesting, thanks for sharing. If you don't mind me asking, was there an argument you had with this person or was it rather an explain situation? Did you know each other well?
Choosing your battles wisely seems to be good advice. I think it's a good quality, if people can concede if they were wrong. I hsbe the impression that being wrong is too often sanctioned or frowned upon, whereas a more accepting, forgiving stance might make it easier for people to admit their errors.
Fantastic. Great name for protests too. Go get 'em.
