Having respect and speaking with kindness would be a good start Cam. Not demeaning people and calling people vile things would also be a plus. Being a man and not thinking it's normal to use filthy langauge in front of anyone (including children) swear and carry on would be another. These would be a start.
One of the programs we work with our teenagers at the College is treating people the way they would like to be treated. We use a compass question in would you say these things in front of a police officer or your mum or nan. If not, why do you think it's then okay to say things to others?
Our focus is bringing up young men to be highly moral and excellent citizens and not bowing to the filth that is everywhere in life. We aim to reach up, not down. As we say, the heart of a man is what usually he learns at a young age. Making the right choices of friends/people you associate with is critical at a young age.
