There are disagreements in any community. Online communities...doubly so. The Kemper Forum is one of the most civil places I've *ever* seen online.
That being said, I think SinMix is right at home here. He's opinionated, sure, but he's never broken the rules. What's more, he's probably responsible for selling more Kempers than most if not all of us reading this thread -- I know two people in my town who bought a Kemper specifically to use his profiles after recording with me. He's also the most generous person I've yet to encounter in the commercial profiling community.
Disagreements happen. People should not be banned and chastised unless they break the forum rules, somehow. There is a language barrier, sure, but unless we have something highly subjective (and thus easily abused) like a rule against rudeness (and, in my view, he's not rude -- just opinionated), he shouldn't have been banned.
