My husband was an elder, 10yrs before he stepped down. The reasons were cumulative but it all hit the fan when he was a visiting speaker at a neighboring congergation. Our son, 13 had cut his own hair, shaved the sides, normal on top. He showed he was sorry and the situation was resolved and we attended with dad to his speaking assignment. At our next meeting the other elders informed him that he would not be giving public talks until further notice. Why? A brother had complained about our son's haircut, too worldly - fadish, and that he did not have his own family in control so he could not teach others.
Aside from the triviality of the whole issue, what exactly did they expect your husband to do after the boy had cut his hair? Shave his head? Nope, too faddish, might be mistaken for a skinhead. Make him wear a wig? Nope, too effeminate and vain.
