Its not Dessie's passing that has caused jocularity but more your rather OTT response to the banter. At no time has the animal been defamed or insulted but somehow you have taken offence.
Makes me laugh some people getting upset at the passing of a very successful horse who has lived a long and pleasant life for a horse. Why not get upset about the horses that regularly get put down after falling. What happens to all the horses who don't win races ? End up as Pedigree chum don't...
I think you need to get off your high horse, its just another hurdle but you'll get over it. No need to saddle us with your unbridled love, we won't take a fence.
