I agree.
Whether or not they are the same person, one thing is clear: it's not worth feeding their fire by responding to them just to argue about who is a parent on a team. They both say things worth debating from time to time, but in the end those discussions seem to always turn to accusations that the other party in the discussion is a parent on the team, as if that is somehow sufficient to invalidate whatever that person may be saying.
I'd love to debate hockey topics here, and not have to spend time arguing about whose kid plays on what teams. That's not worth discussing, except where it has an actual bearing on a conversation rather than merely being intended to somehow belittle a parent.
For the record, my kids don't play for ANY of these organizations, and are both A players. I enjoy this discussion board when there are useful discussions about hockey and related topics. I don't see how arguments about who has the bigger stick are useful. It's best to just ignore the boorish behavior (when it happens, and from anyone) rather than giving the guys who post that stuff what they want: attention.
Just my $0.02.
