Don't take everything to heart. It's not your fault you were never educated on conformation. I wasn't either, and I have learned a lot from this board. Just grit your teeth and smile, it may seem insulting but it really isn't meant that way. Everyone is just appauld that someone would allow breedings to something to conformationally challenged. You can find a lot of half decent, still not stallion quality-stallions with very minimal conformation problems to breed your mare to.
