yes, it is an interesting topic.
I have to say your description of hardcore Tibetan Buddhism, where they want to eradicate the individual sounds like a lot of bullying.
As a teenager, pre-cult, I liked the yin yang symbol, I liked the way the two sides curled together and had little dots of the opposite colour in their hearts.
And I do think there's something to the idea of there being that exception that proves the rule - a time when you do the crazy not the wise.
I think those teachers are exploiting an instinct there. I think the learning is hard won.
