If an act or practice is dangerous, then that needs to be dealt with certainly, but on its own merits, if "merits" is the right word here. ...I think we're conflating more than one strand of discussion here. I don't know how to put this clearer than my more concise stating of it that you quoted, but I'll give it a try.
I might prefer reading as a hobby to ...bungee jumping, say, but to therefore suggest and imply thereby that it is therefore more "normal" and somehow more natural, I don't know that I agree, at all, with that line of thinking. Certainly no one should be pressured into extreme adventure endeavors and sports. But nor should anyone be pressured into reading-for-fun either. It's an individual thing, and up to each individual's own predilections and preferences. ...And if some endeavors, some hobbies, can lead to danger even death --- like bungee jumping, or even simply working out or running, or like an overly sedentary lifestyle --- then that speaks to arguing for both general awareness about the risks as well as the requirements and dangers accompanying these pursuits, and what precautions one might reasonably take, as well as specific awareness about one's own health and tolerances etc. But none of this translates to branding some hobbies as somehow, for all purposes, good and right and kosher, and some less so.
Likewise with all kinds of sex acts, be it "vanilla" missionary, or as you say strangulation, is where I was coming from. What your story, your link, points to is, one, that people be aware this is a risk and factor that into their (instinctual or sit-down-and-think-about-it) calculations, and consider what precautions are desirable (even necessary), and all of that: but none of this suggests, to me at any rate, that some sexual practices are therefore better or worse than others, as long as there is full informed uncoerced consent. Focus on the consent part, is what I'm saying, focus on whether there is coercion of any kind --- but focusing on the nature of the act itself, is going down the wrong what-have-you completely, as I see this.
You do well, in general, to point out the risk from including strangulation into one's repertoire of sex acts, sure; but it's a whole separate if tangentially related discussion really. It doesn't make the argument you're trying to make, at all.

See, this right here is a line of thinking that I simply don't grok:
How does it matter, what percentage of humanity does a thing? Regardless of whether 99% of everyone does it, and regardless of whether just 1% of everyone does it, it makes no sense at all to do a thing --- be it getting off on playing at choking your partner, or be it just simple sex, or even hell just kissing your partner while fully dressed --- unless you are fully into it, and also, importantly, your partner is fully into it. What matters the nature of the act? (And no, don't again bring up specific risks attached to the act, because while generally relevant certainly but like I said that's a separate different discussion that's irrelevant to this specific focused discussion.) What matters what proportion of people at large do it? The only thing that matters is consent, full complete uncoerced consent, and not just consent but enthusiastic consent. That's what's healthy --- and natural! --- to do ourselves, and that's what's healthy to teach youngsters to be doing. The focusing on the consent, one's own and one's partner's: and not on specific sexual acts.
