Lineageholder, it's not a worldly concern when how we look affects the opinion of others, and the message we are trying to deliver.
Since not everybody who says they do the practice really does it, then letting somebody at a mic, might be counterproductive if they are not skillful. when have we gotten a dialogue? When has there ever been anything but censorship about us? The Dalai Lama knows he looks bad, some people who are really with him may want him to come off looking better than he really does. At NKT Centers for instance, anyone is welcome, which is great. But just because someone goes to a place doesn't mean they are really with Shugden--- look at the NKT "survivors." Do you really believe they think they are in a cult after being ordained, being there 7 years etc. if they didn't already think so to begin with?
We need to be careful who is speaking for us, or it will not help the ban, because we will get someone who either makes us look bad, or downplays the issues, or "converts" to the Dalai Lama upon seeing him.... I mean... please guys, let's do be careful.
So in summary, being concerned about how others perceive us is not worldly when the motive is bodhichitta, we want to make sure that people come to the Dharma so most people don't run around naked these days like Milarepa did, even the Milarepa emanations (like Gyaltrul Rinpoche, recognized by the 16th Karmapa as Milarepa) has always worn clothes anytime I have seen him. So, you know, Milarepa has no worldly concerns about clothing, but the beings of this day must have needed him to wear clothing in order for them to wake up so so far he has been doing so, at least that I am aware of. It helped the beings in old Tibet for him to show up naked and singing songs.... so he did.... but the situation we are in determines the presentation; the pure motive of wanting people to understand our position so our protests can be effective, and so the ban can really come down is what we are after here.
