Oh, I'm not opposed to adopting from rescues. I think that handled properly, it's a great thing. I have recommended to several clients that wanted a pleasure type horse to look at the rescues first. I know there are good places out there that help as many as they can, while still being reasonable.
But having said that, most rescues (not all, but most) have a certain area or distance that they will adopt to. And when the rescues within your specific mile radius make it so difficult, and the others say you are too far away, it's hard not to end up cynical. I am all for vet and farrier reference checks, have done them myself, but (at least around here) when a half dozen different people have to inspect you, your other animals, and your property, because there is no internal communication, and if ONE of them decides that because you scratch your nose the wrong way, that you aren't fit to adopt, or they decide that 5 or 10 years down the road (since our local rescue has the stipulation that they can do random spot checks for the life of the horse without warning) they want to pop in, and then if they decide they don't like something you are doing, can just take away a horse that you have invested years on, well, that makes it hard for everyone else. Personally, I'd hate to think that someone could just show up at my farm, unannounced and demand to see a horse that I adopted years ago, and have the knowledge that they could come right back with a trailer if we had too much mud or not enough bedding to suit them.
I will say it again though. NOT ALL RESCUES ARE LIKE THIS, but I would hesitate to adopt from one that was. It is up to the buyer, or the adopter to do their due diligence and weigh all the options.
