"It’s time for the Grand National again – that curious time of year when people who claim to like horses gather to exploit them, often hurting and killing them in the process.
Since 2000, 48 horses have died at the annual festival that the National is part of. Others have suffered horribly with broken backs, necks or legs, severed tendons, or heart attacks. This is the reality of British horse racing."
If you use this as entertainment, the blood of murdered horses is on your hands as well.
Would you bet on a race where human beings fell and broke their legs or necks and had to be shot? At least they would have consented. Horses cannot consent to this life.
Would you be "fine" with it as long as it hadn't happened since 2012, despite horses dying after the race from their injuries since then?
Please don't be dazzled by the so-called glamour of this bloodsport.
