For me, it depends on the horse. Most horses would get a "come to Jesus" moment if they turned their butt to me with the intention of kicking, but there are a few horses I know that I would never try that with.
For instance, there's this one mare that comes to the camp I work at during the summer. She's one of those really cow-y, sassy, dominant mares that believes in her way or the highway. She used to have a real issue with turning her butt to me and acting like she was going to kick and the first few times I really got after her. However, that just made her angrier and she started trying to attack (like teeth bared, butt swinging, etc) me whenever I got near her. It was basically because I was trying to tell her what to do "too much" in her opinion. After a few times of seriously fearing for my life (and this mare is little, maybe 13hh, but built like a tank) I just started ignoring her jerk moves. I would get myself into a safe place near her and keep doing what I was doing. I wouldn't let her scare me into giving up but at the same time I didn't try to manhandle her. This last summer, our 3rd summer working together, I was the only person she didn't even try to bully. She knew that I was always going to "win," so there was no point in fighting, yet my "winning" wasn't bad and she never got hurt because I "won," therefore she was willing to let me "win."
I just had to show her that I was more beastly than she is. And now, she's totally fine with me. She used to be hard to catch in the pasture but I don't even have any issues with her being caught anymore because she knows she will be caught and she doesn't want to move her fat butt more than she has to!
I also feel like a lot of times people look at their horse and say "this horse has an issue" instead of saying "I have an issue that is causing my horse not to see me as his/her leader, and the result of that is that my horse is biting/kicking/what have you." I'm not saying that you aren't being a good leader, I don't know you! But I'm saying that if your horse is trying to kick you, you might want to look at your leadership technique and see if you are being a worthy leader for your horse. Can he/she trust you to make all the really critical decisions and come up with a mutually beneficial result? Or does he/she expect that in the face of "danger," you're going to get all anxious and unreliable? Are you predictable in what you require from your horse or do you have different rules everyday?
Horses rely on having a strong leader in their life and if they don't feel that you're a good leader, they WILL take over that role. Then, when that happens, you become another horse (in his/her eyes) to be "disciplined' when you get "out of control."
It's totally a learning process, but if you treat the base problem, if there is one, the symptoms will more than likely go away.
Good luck! And sorry for the novel, I kinda got going. Haha
