No, I don't favour an argument/debate but as I see it most sports involve humans principally who go about their chosen sport aware of the risks, wehereas in some horse races - and certainly not all - the horses are pushed by humans and remain ignorant of the risks they are taking which may end in their death.
Although I'm not a fan of gambling or horse racing I think the whole spectacle, Ascot and all, is a fine thing, part of this country's history and imagine a nice day out for a lot of folks, long may it survive, but The Grand National?
In my opinion it belongs in the past, time it was scrapped, or just run the race without the hurdles, perhaps.
