The Dharma excludes nothing. Silke's demand that we turn away from those who are suffering (like the monk who has been living with HIV for 20 years) is deluded and cruel, and has more to do with New Age narcissism than with the Buddha Dharma.
Buddhism goes straight to the source of suffering, with honesty and compassion. We let go of our suffering by seeing things as they are, without attachment. And, like the Buddha, like Bodhidharma, like Dogen, like every authentic Buddhist practitioner through history, when we see clearly then we see what's harmful, and we take strong and compassionate action to offer a remedy.
