Hi Harry,
If you’re self-disciplined and work hard on your own everyday, you can use the once-a-week to get corrections and learn new material (when the old material is correct). That’s the easy part.
Sihing shouldn’t argue about who is right or wrong while leading a class. It’s disruptive. Actually, Sihing (pl.) should never lead class. A sihing (singular) should lead the class and everyone else follow to prevent such problems. Then, if they disagree, they should take it to the sifu outside of class for resolution (and hopefully they’re experienced enough not to waste time on contextual differences).
There’s probably not much you can do about it, however. So, in the situation you’re in, you need to decide if its adversly effecting your learning and enjoyment of WCK enough for you to seek instruction elsewhere. If you’ve got enoung training under your belt, and are a good analytical problem solver, that you can figure things out for yourself (using the WCK concepts you’ve learned), then double check with your sifu when he’s around (ignoring the squabbling sihing), you’ll probably do okay. If you’re just beginning and find you need more help, then you’ll have to take steps.
Understand, many Western MA schools have profoundly misunderstood (or have deliberately changed) MA etiquette and interpreted it in a rigid caste or hierarchy or a near facist social organization. This is nonsense. You’re a member of a martial family and you have certain rights and certain responsibilities. If you’re a very close student (inner door) of your sifu, your job is not to shield him from his own problems (though you will try to cover for them), but to address them with him and try to solve them. Likewise, as a sidai (teacher/younger brother), you have a responsibility to help your sihing, and if they are disrupting class, you might want to consider talking to them (privately, of course), and pointing out how its adversely effecting your training. If they’re worthy of being sihing, they’ll want to help you just as much.
There is a danger, of course, in that you may lack as a beginner the experience to determine when a sifu should be trusted (when he is challenging you to think for yourself, for example), and not (when he has become negligent in his role as sifu), or when sihing may need your advice or not. But in the end, you need to take care of yourself and enjoy what you do. If this means going elsewhere, you’re lucky to live in a time when there are many great martial teachers around who are willing to teach.
Wow, heavy topic…
