Contemporary research into moral reasoning suggests that, to do otherwise, would be counter-productive at best, and at worst can serve to entrench the harmful beliefs further.
Children are our future. Each child deserves our best. Modelling empathy is the beginning of conscience. Encouraging curiosity, and the love of lifelong learning, challenges them. Praising efforts encourages them to make rational, compassionate decisions, and to be active.
Compassion = considering what the other person wants and treating them accordingly. Choosing to help, rather than hurt or ignore those in trouble, or with less power than oneself. NB. If you haven't asked what the other person wants, you can't treat them compassionately.
Live happily: What better feeling is there than to smile or to get someone else to smile? Love broadly: People think differently, respect that. Think critically: ensure your actions are moral and you don't blindly follow others or believe non-evidence-based theories.
We cannot assume that how we would like to be treated by others reflects how everyone in our lives would like to be treated. Before we act, we must have the patience and insight to request information from those around us on how they would like us to treat them.
