Don't be the swine that tramples someone else's pearls.
How easy it is to criticize something we find lacking, only to later realize that it is precious to someone else! In our quest to justify ourselves and our opinions, we devalue something that is a treasure to someone else. It can be anything – a possession, place, organization, church, hobby, idea, person. It does not matter. Don’t let your pride in your own opinions devalue the treasures of another person.
