Don’t believe in reincarnation? Do believe in Gay Rights? There’s no such thing as a Buddhist heretic.
The tradition of Buddhism (I’m Buddhist, this is what I’ve been taught) is this:
“Always trust the principle one.” Meaning, trust your own judgment before any outside (theistic) wisdom.
“Do not follow what I say. Only do what I say if it meets your experience.” ~ Buddha
Dalai Lama: “If Buddhism and science conflict, we go with Science.”
I don’t have the exact quotes, but that’s the gist.
PS: that’s why, say, if reincarnation doesn’t makes sense to me, but is a Buddhist “belief,” I (after much consideration and study) toss it.
