There are good and bad people on all forums. There are some people that either say things in a harsh manner not intending to sound as bad as they do or... people that enjoy hurting others.
Many long years ago I had this Saddlebred filly. I was talking to a "friend" about my new purchase and that there was another filly there to chose from. She says "you should have taken the other one, I liked it's bloodlines better."
I said "Mine has multi world champion bloodlines, and I liked this one better."
She said "well, you won't win anything on that horse."
Fast forward a few months, My horse is beating her horse and all the others week after week, show after show.
She gets a different horse, mine still beats that horse so she says "Man, the judges certainly seem to like those Stock type horses around here." There were about 12 of us around when she said that and we all stood there with our jaws dropped. The horse that I had was about as refined as could be. She was gorgeous.
Jealousy gets people nowhere. You take those comments and dump them in the garbage. You love your horse, who cares what faceless strangers on a random forum think? No sense even getting worked up about it.
I also loved beating many of the snooty kennel club people with my rescued dogs in obedience. Proves what hard work and love can do. Some people just don't have the heart to love or the skill to work with something that doesn't start out perfect. Be glad you don't fall into that catagory.
