From my perspective I've been gifted with knowing certain things and I don't see any reason to mince my words. Mincing words is what has gotten us into this mess in the first place.
As for how the medicine should be delivered - I think that's a very difficult issue, and is ultimately best decided by each individual, since only they know for sure what their own motives are (hopefully). But the issues you raise are good food for thought for anyone.
Personally, I'm not interested in beating around the bush and pandering to people's precious feelings. The situation is too serious for that. The very last thing I want to be is misunderstood, and I've learned through experience that if I sugar-coat my words, or soften them in any way, then 95% of my message is lost - which is effectively all of it.
I'm simply not so sure that I'm not just as silly as they are about other beliefs . . . but I'm making the effort.
I respect that. Obviously I consider that I'm working from a position that is a little more secure, and less vulnerable to collapse, or I wouldn't be taking the rather bold approach that I am. Even though I'm far from perfect, I do believe that my eyes are open to a great many fundamental truths of which the Dalai Lama knows nothing.
