As a SM, I was called at least once a week by a parent with an opinion of something they saw that bothered them. Sometimes more than 1 a week, rarely less. And you would be amazed of what bothers parents. Every SM has a strong opinion to someone, especially if they firm with how the program is run.
All I can say is if SMs, or strong leaders, don’t learn the art of listening, they will have continued frustration and drama. Add the skills of patience and humility because sometimes the SM, or strong leader, is wrong.
