The thing I’m still trying to get my head around, and it is not victim-blaming, just trying to figure out how these things work socially, is:
Trainer is a barn-hopper with a bad reputation. Kicked out of five or six barns? Known for blowing up at show stewards and getting her students kicked out of shows? Seen to publicly abuse her horses? Puts her students in dangerous situations, on dangerous horses? This in a small community of riders where there are not a lot of English barns? All of this is quite possible.
But what I don’t understand, if the bad behavior has been so egregious, so public, if she has burned through presumably all the other barns in the area: why doesn’t she have a bad reputation to the extent that her business is faltering, or that everyone isn’t warning everyone else to stay away? In general, if someone has done a list of terrible things to one person, they have done the same things to most people. And horse people talk. Maybe not publicly, but they certainly talk privately.
What is the trainer offering that makes up for her bad reputation in the community? Is she so high-ranked in the sport, and giving people such a good line about how they will excel with her, that people ignore other red flags? Do her students excel? Or what?
