As for your comments about the coach in question, I�m unaware of the details but would caution you that you are walking very close to needing legal representation with claims like that. I believe a defamation case If your comments are untrue would be a slam dunk. Luckily any adult can see thru them as �hate speech� towards a club you despise.
My experiences and opinions of the coach are my own but are very true. I recommended that the poster could/should talk to the parents of boys on the two teams that requested a new coach. I do not believe their opinions and desire for a new coach amounted to their defaming the coach.
Perhaps shaming children and saying they don't have the talent to make top teams would be a better case for defamation if untrue.
