This forum is one of folks who care about horses. No doubt about it. But , we have to accept that not everyone has the ability to care for horses in the way we might think right. But, if you understand some of the environment that the horses live in, you would know that they are doing just fine.
There are horses in other parts of the world who would be better candidates for pity.
Also, it's not really fair to be judgemental of how other people care for their animals if they themselves struggle for their daily needs.
