What's wrong with that? You keep horses your way, and others will keep them their way. My boys have stalls, but they're only used when the weather's bad. I personally don't believe in making an animal stay outside when it's cold, windy, and rainy/snowing.
What I dislike is when someone with a year or two, maybe less, in horses thinks they know more than I do, who have had them for 3 decades. Nobody ever knows everything about horses, but the noobs tend to think they know more than the truly experienced for some reason.
I was referring to people thinking that horses should be stalled the majority of the time.
