Horrifying and I didn't click through either. Just too cruel and oblivious. I have a built in revulsion at those who mistreat the vulnerable, whether human or animal, and hope that most people share it. If you are more focussed on your photo op than a creature's existence, I don't want to know you.
Unfortunately, my state now has a high number of children who died at the hands of others (frequently those entrusted to care for them). Abusing elders, kids, people who are frail or different is just another side of the same coin.
Tragic. You are not alone, Una.
