Look, no one was being snotty until you kept insisting that this farrier is so good--even then most were exasperated, not snotty! Just because we were truthful about how poor this last trim was doesn't make us snotty.
I can understand if you are frustrated over the lack of a good farrier as I have been there too. We had a good farrier years back but he retired and the ones that came along after we're not good at all. The only difference in my case I could go out and fix up whatever the farrier did wrong--and so I gave up on a farrier and started doing all of my own trimming. More work and harder on my back but it saved me some money and the horses then were trimmed properly. Never would I defend those farriers I tried and never would I say that they are good farriers!
Perhaps you are simply frustrated too but that post that I quoted earlier came off as one of the most snotty of all.
When you insist that a farrier is good when he so obviously isn't --well, most of us just don't feel much like offering any more info. I have tried before to teach people who have no real interest in learning --big difference between them and those who truly want to learn and are willing to listen and actually see what is being explained.
