Frankly no. I dont know where you are going with this.
I read a few posters saying that they have no personal knowledge of Rebirth and that they therefore are agnostic on the subject.
I have read posts to the effect that the whole concept of Aryans has become a symptom of hierarchical sclerosis within Buddhism.
I have read NO poster who has gone for refuge who teaches that the Buddha did not teach kamma as delineated in the Pali Canon and is s/he is concerned that it will be misunderstood...but not withstanding they are going for Refuge anyway.
When we go for Refuge we dont leave our brains at the door, we have to understand what it is that we are committing to. By interpreting kamma in a particular and unique way, Ambedkar demonstrated that he didn't know what he was committing to. He was looking for an identity for the Dalits and Buddhism seemed to fit the bill...however his superficial understanding of Buddhism seemed to him to condone the Hindu view...so he junked kamma as understood by 2500 years of Buddhism, in favour of a political position that suited his purpose better. That he did this is hardly a matter of dispute.
Had he lived who knows how his views might have matured. But he didn't..
Some years after Ambedkar's death, Sangharakshita led a mission to the Dalits, and much of its thrust was to correct certain distortions that Ambedkar has introduced into his version of Dhamma. The result was a huge wave of Dalit conversions to a version of Dhamma fully convergent with the Canon.
There is though a large rump of "Bhim" hardcore followers who still insist that the Buddha was in fact a political reformer who did not teach kamma as found in the Pali Canon...
And they refuse to have anything to do with mainstream Buddhism, they are in fact a cultic group within Buddhism.
We have no way of knowing had he lived which group Ambedkar would have been associated with. We do know for a fact that during his life he was associated with the latter view.
The going for refuge is the door of entrance to the teachings of the Buddha.
