I don’t think its a matter of people “loving” barbed wire but rather that people are pointing out that there is not necessarily any problem with a barbed wire fence. As I mentioned EVERY cattle station that I have ever worked on, had barbed wire horse paddocks; and when your horse paddock may be a hundred acres +, and contain 50 horses or more, fencing the lot with nice wooden posts and rails is infeasible unless your a billionaire or something. Personally, if I had a place and was breeding horses (which, one day, I hope to have) then all wood posts and wood rails, or box steel and box steel rails would be my preference. But that can run into the thousands, or thousands of thousands, hell, barbed wire and steel posts runs into the thousands, I have a cousin who does fencing contracting on the side to his real job, and he almost makes more money off the fencing than the real job. The rule I was always told about though is, if you can, always have the paddock your stallions are in fenced with big wooden posts, especially if you intend having mares in the next paddock over; which its always advisable not to in the first place if you can help it. I heard of at least one stallion that impaled himself and died on a steel fence post trying to get at a mare across a fence.
