I would allow that you are *technically* right, though I would suggest that "safe, sane and consensual" is a sufficiently agreed-upon norm within the kink community to make it pervasive and generally agreed-upon. Frankly, if someone was pursuing what they called "kink" and it wasn't consensual, I would have serious questions about their behavior.
I think that depends on which kink community you're talking about. I know a number of folks who prefer RACK (risk-aware consensual kink) to SSC.
