Thank you for your replies everybody.
As you may guess, my study conductor refused to reveal the name of the complainer. I told her it is best if SHE (we both know who she is anyway) come see me direclty to address the issue, otherwise there will be no change in my attitude whatsoever. To wich she replied:"you might have valide reasons to behave that way, but as real christians we must put our difference aside and swallow our pride to maintain the congregation peace. (She pointed out some verses in the bible). You might not realize but you are not just hurting sister x. Your attitude may be stumbling others members". I ended up the debate by saying That being distante is the only way I can preserve my inner peace (and that of the congregation by extension). Since i'm not disrespecting anyone, i'll continue to do so. It is really common for the members of our congregation to ignore each other. that's nothing new under the sun. Nobody will stumble.
you know what we say about hispanic and black women: they are very assertive (I may be out of line. Don't quote me on this one :-p ). Guess what? I'm a combinaison of both. In my culture, we don't believe in passive agressivity. Ever since I've been affiliated with the JW's i've learnt to be less confrontational wich I think is a good thing. I deal with people that I want to deal with, and ignore the ones whom I can't learn anything from.
