How silly to "hate a breed". Goodness there are good and bad horses in every single breed. Lots of the bad is due to stupid handlers.
I board at an Arabian ranch so I am surrounded by them. Yes, they are sensitive and a little spunky shall we say. But, all of them are well mannered and well trained. Even the stallion out there, Sada, when he is in his little paddock he will run at the fence, turn and kick it...blah blah blah. But if you fuss at him he instantly stops
until you walk away and he does it again. But, on the wash rack or under saddle, he is always obedient. He was fussing at Biscuit on the wash rack a few months ago and I fussed at him and he instantly obeyed.
He used to scare the pants off of Sarge or Sarge thought he was crazy, one of the two. Sarge got out of his pasture one day after I had put Red up in a stall due to a health issue. He went looking for Red and encountered Sada. He and Sada must have had some conflict because after that, when Sada would see the little bay QH he would cross to the other side of his pen and stay there. LOL he was brought up one day and was thinking Sarge was pretty dang cute until he realized who he was. He shut up instantly and was quiet as could be.
Arabs are smart, full of life and spunky. Some of the ones out at the barn are lesson horses and you could put a child on them. The original old stallion, Amir, was a child's lesson horse. Not to many studs could be trusted with a child!
I have QH's but I ride with a variety of horses, QH, Paints, TW, Arabs, a Quarab, Rocky Mountains, a Morgan/Friesan cross. They all are wonderful horses.
Just ignore people with that attitude. It is the same as people saying QH are just cow horses, or just stupid push button horses. Or lazy or whatever the insult is. I ignore it. Biscuit is pretty dang special to me and so is Sarge.
