There's an argument for the free expression of kink being entirely situational, given the nature of people to be averse to things based on entirely irrational feelings (just because you have a "feeling", however strong, that something disturbs you, doesn't make your objection to it any sounder; it's the context that matters, not the aversion.) The line isn't something to be drawn on whims and instinct, but where the real effects of the act lie in actuality. Someone minding their own business, just in bondage, isn't going to be any harm by simply existing in public, for example.
I'm not entitled to control the myriad methods people use to show their affection, or express themselves, so I don't find displays of kink that would never impact me or others beyond triggering some subjective repugnance or aversion to be objectionable. If I start drawing the line at subjectivity, the line would have no end.
