I'd much rather have a forum where people question EVERYTHING. It keeps on our toes and our minds open. Yes, it's annoying at times, but that's okay. It's better than only being around information that feeds my current bias, which could lead me to missing valuable information.
I love paleo, but I don't think it's perfect. Also, I won't let my love of the paleo concept to block out new information that could tweak or alter my diet and lifestyle.
