1. One shouldn't compare hitting humans with rotan/stick/etc with hitting pets/animals with the same things. Why? Because humans have brain/akal. Humans can shows clearly either they are hurt, sad, angry, etc. Animals? They cannot shows you clearly all that. All you can hear from them is their barkings, meowings, purrings. If you hit your kids with rotan/etc, if they really cannot tahan or regret it, they will shout it out to you, they will tell you, and you UNDERSTAND them. Animals, you can hear them, but you CANT UNDERSTAND them. Humans can protect themselves for god sake. What animal can do? They run off from your house also, they know that they cannot survive outside after spending a long time away from outside world. I have cats myself (7 of them) and once in a while i do hit them to discipline them. But I use rolled-up newspapers, magazine, my own hand. And I hit them maximum 3 times. After I leave them aside for 5-10min, I will take them back into my hand and love them. Shows them I am not angry with them anymore. What she did IS WRONG. Plastic hanger wont simply broke if it just 1 hit. Take one and try it yourself. Hit your mattress maybe. But why does she has to use the hanger? Bad childhood, maybe. She wont use her hand because it will hurt her hand. You can see her pics yourself that she's the typical <insert race> girl, who only love their pets when they wanna take selfies, wanna show the world how cute her dogs is, or how cute she looks with her dog. You know what I'm saying.
2. Why compare disciplining kids with military style? Disciplining your kids doesn't have anything to do with military. Everybody who joined the military is above 18 years. Parents who hit on their kids would probably stop when they reach 15 (maybe?). They knows when their kids reach 16, they would tend to be more rebel. You have 15 years to raise your kids the proper way. And like I said, comparing with military is just stupid.
3. Jangan panggil orang bodo lah, bodo! Heard that term before, right? Come on.. relax! Why would YOU wanna be pissed off? Everybody have their own opinion, wasn't it?
TL;DR : WHAT SHE DID IS WRONG. INSTEAD OF TAKING PICS AND POST IT ON FB, BETTER CLEAN YOUR BATHROOM/PLACE/SPOT/LITTER BOX FOR YOUR DOG. THEY PEED EVERYWHERE FOR A REASON. You quite bodoh ler. If given a chance I would like to meet your parents and tell them how retarded you've become.
