I've eaten horse a lot, in my youth we had a dedicated 'horse butcher' in the city near where we lived and I remember as a kid 'travelling' with my dad on my tiny bike to go shopping there once every two weeks or so. We weren't very rich and horsemeat was cheaper. Sweet memories, it is now a 15 minute bike ride and the world seems smaller.
I still think there is nothing wrong with eating horse but the last years we had some scandals over here (Netherlands, EU) where horsemeat illegally was mixed with beef and sold as beef. Apart from that the hygiene wasn't ok so, in the end it's horsemeat that gets the bad name while basically it is a good protein source. At the moment I don't know any address where to buy, a pity really.
Anyway, as the original poster, I won't be coming over to cull your feral donkeys, especially when they're protected by whatever fancy law you have. We have our own 'people who live in cities and make laws about things they may not be knowledgeable about' and 'people who think animals should be allowed voting rights'.
