I think I once read somewhere the suggestion Slim is on a long-term moral crusade against Murphy.
Whether there's any truth or not in that, it seems to me to be a subject Slim is passionate about, which certainly makes for eye-catching reading.
I'm less animated about it because people in racing (and in life generally) seldom interest me.
Trainers and jockeys, to me, are just walking sets of performance stats, whether they are "good" or "bad" people, or "good" or "bad" ambassadors for racing, doesn't matter to me.
There are one or two people in racing I have formed a casual remote liking for (though if I actually met them and spent time with them - something I have no desire to do - I might change my mind).
And there are plenty I have a casual dislike of - Murphy is one of those I've slowly over time developed a casual dislike of.
But I don't need to like someone to bet the horse they're riding or train if I think it's value at the odds and that's all that really matters to me tbh.
