Thiiis. There are safe ways to practice kink, and being kinky isn't the same as being abusive.
It's true that a lot of abusers use the vocabulary of kink to justify hurting people, but it's like how a lot of health grifters use the language of science to scam people with dangerous or ineffective medicine. Some people spouting bullshit doesn't mean that valid science, or risk-aware consensual kink, doesn't actually exist.
It is NOT safe or consensual to choke, smother, or suffocate someone without talking about it first, making sure you both understand the risks and what is more or less dangerous, making sure you're both into it, and having some way to communicate "no, stop" that works and will be respected even when one partner (as is often the case here) cannot form audible language.
(Edited to add: People in the notes are like "Even only 30 seconds is dangerous!" and sorry loves, it's worse than that. You can completely pass out within the first 10 seconds. There's literally no amount of breathplay that isn't hazardous.)
Anyone who tries to choke, strangle, or smother another person without this kind of willing and informed consent risks grievous harm or death to that person, severe legal penalties to themselves, and whether through ignorance or outright malice, is a dangerous person who merits every effort to stop or get away from.
This is true whether you are a man, a woman, trans, cis, gay, or straight. It matters whether the other person is a lover, a parent, a stranger, a friend, or an enemy. If you feel afraid or unable to keep yourself safe, please reach out to a domestic violence organization or, if you're a minor, a child help line for emotional support, danger assessment, advocacy on your behalf, and help figuring out how to find safety.
