Quite the contrary. I go even further than you. Buddhism is just a necessary shell for many which reappears in different forms by different Buddhas. It is just a finger pointing and even it's target moon is illusory. 1) We should respect the condition of many non buddhists but also buddhists. Not just one side. 2) My position is not what you think. I go even further, even Dzogchen/Essence Mahamudra are just shells too. Shells true, yet the best things and concepts and medtitations and path or anything fathomable in existence anywhere, specially in 13 lucky world systems in our large sector and not reappearing in all eras in future either as in the past.
My mantra here has been ChNNR LIKE ALL RINPOCHES WELCOMES ALL REGARDLESS INTO HIS TEACHINGS. Then what happens is different for each person. Sure you can get DI realization first time but if you want to progress you NEED MINMUM ONGOING SHORT ATI GURU YOGA and for maintanance and progression to advanced levels even more practice. Truth be told, my position is much more radical than what yours is. Like I said, the best path after recieving DI or mahamudra pointing out and starting practices like all nirmanakayas of past, is actually our 24/7 daily lives moment to moment as well as certain noble but not necessarily "Buddhist" disciplines. I agree with you and even go further so quite the contrary. But everything in it's place and lets respect all sides' conditions not just one side at the expense of others. Unlike you guys I gave up my all my paraphernalia and most do not know what I believe or practice.
All the best.
Dzogchen masters I know say: 1)Buddhist religion essence is Dzogchen 2)Religions are positive by intent/fruit 3)Any method's OK unless: breaking Dzogchen vows, mixed as syncretic (Milanese Soup) 4)Don't join mandalas of opponents of Dalai Lama/Padmasambhava: False Deity inventors by encouraging victims 5)Don't debate Ati with others 6)Don't discuss Ati practices online 7) A master told his old disciple: no one's to discuss his teaching with some others on a former forum nor mention him. Publicity's OK, questions are asked from masters/set teachers in person/email/non-public forums~Best wishes
