Ok, since obviously a number of people had differing views on what de-sensitising horses is and isn't, perhaps it would be worth finding out what people think it actually is. I'm not asking for or encouraging discussion about particular trainers, I'm just interested to find out what people think it in fact is. I believe that a horse that has been desensitised is one that will not instantly react to outside influences in a way that effects its work. By this I mean that it will stay with its rider/handler rather than worrying about what's going on around it - for example if you're at a show, there's lots of flappy flags etc, and instead of losing it because of the outside influences (flags) the horse listens to the rider/handler. The horse can cope with new and different situations because of its handling and experiences, and does not let its natural fight/flight instincts take over when exposed to new things. It's not that the horse does not notice things, or that it is dulled to aids, it just listens to what its rider/handler is asking it to do over the scary/different influence. I realise not everyone will agree with that definition, and that others may phrase it differently, just looking to find what other people think.
