There are a few topics that generate serious responses and often not done politely. We're supposed to be about helping others enjoy a common interest, right? Many times I've wished folks had to sign their real name to a post...bet they wouldn't be so obnoxious. Even worse when it's a newbie that just steps into it. So sorry, it's not usually like that.
We are serious dog people, too. But I wouldn't consider chewing someone out or making disparaging comments online. It's very possible to disagree with respect. Wish manners and consideration would make a comeback.
