judging people wont get anyone anywhere.
what i remember of chassidus's interpretation is that what Asher said is with regards to oneself, while when looking upon others it must be with the right eye. Since when do we care about aveiros? When its someone elses?..... I was once talking with my boss and i reluctantly mentioned a personal hardship, and he responded with a sigh that everyone has his peckle. But again, thats with regards to ourselves, when looking at someone else they must be perfect and not deserving of their respective peckelach. Really, why does it bother you?
What matisyahu does is terrible, and he must be denounced and disowned by the greater jewish community, as he has nothing to contribute, and is addmittantly contributing to the world his own expressions of himself, not those of judaism. I would assume that as soon as we leave our neutral stance regarding him his popularity etc will cease. I can safely guess that only a small minority would deem his work positive in that respect.
We're scared that if he's unzere we can denounce him, but if not we must be mekarev him, although he claims to be unzere and allows us to accept him as long its independent of any denouncement of whatever demands it.
And thats what i recall of chassidus's interpretation of kiruv, the famous "bringing people to Torah Judaism, not bringing the torah to them" and allowing them justify their pritzus through a vale of chanuka.
I noticed briefly in the article on the blog that they compare him with carlebach. i would prefer to liken him to zalman shechter. No speakers or educators or rabbis are without bias, sechel inherently has netiyos, but to make those mutar, consiously, (and publicly)...
Carlebach regocnized that what tanya speaks about with regards to focusing on asei tov rather than sur mei'ra means that everyone is perfect, 100%, regardless of his aveiros but not in spite of them, not denying them. And even our own.
Now if someone comes and tries to exploit that, is the answer to do what a non-chassid (or whatever) might respond with? The problem with chabad is that (for whatever reasons) we (practically) arent able to do two things at once; שמאול דוחה וימין מקרבת. Chassidus interperats that the essence of a Jew is a נושא הפכים...
And maybe if we focused more on our own lack of excuses and justifications we would get further in that
