You sound like a very loving person and I'm sure you deserve to be confident in your "breeding" activities. I think the key is to not allow yourself to be bothered by these sort of posts and to know yourself. There should not be black and white opinions of the type of breeders, only the irresponsible pet owners/breeders. Sounds to me like you're one of the good ones, no matter what label someone will put on you.
Don't be ran away from the site, just be confident that you're one of the "good" ones
