Well, it's the same as with anti-natalism:
People who don't care about this stuff, will still have kids / take 'consent risks' to have sex.
An important complication about the topic at hand is that a lot of human courtship / flirting, involves plausible deniability. Eg extensive eye contact in a bar can indicate sexual interest, or perhaps you just have a booger on your nose.
Similarly, status and power play are just as much ingrained in human psyche as sexual behaviour. So there's lots of overlap. Lots of people enjoy when their prospective mate is a bit brazen (or, the opposite, plays extra shy).
Playing with social convention is a big part.
Human behaviour is messy.
I think the discussion of explicit consent is really intended as guidance for children/teenagers who don't the dance yet. For experienced adults it's possible to navigate all of these grey areas and read the underlying signals while being crystal clear about playing within the boundaries which are acceptable to both sides. But for kids who are still figuring this out, it's perfectly reasonable to suggest that people use their words and be unambiguous.
If you never bother attempting to initiate sexual activity, you're pretty safe from those who would use the sex act to alter your life. And if you eschew participating in collective sex-culture, its pretty easy to keep this under control, at a personal level.
All this does is make people think twice. If you're married and trying to have children how can any craziness ever happen? Not sure what "collective sex-culture" is, but it may be what many just call "promiscuity" (which is kind of my point).
Conservative societies generally had more sex than we do now.
If you think "Victorians" are what is meant when someone refers to a conservative society, then you might need to read a few more books. Its quite possible to be conservative on the subject of sexual activity, while also voting Democrat.
Edit: it unfortunately looks like you've been doing this repeatedly. That's not ok, and we ban such accounts for what ought to be obvious reasons. Please stick to the rules from now on.
If you get consent from your partner, have sex with them, and then your partner changes their mind about it afterwards - for any reason they determine under their own agency, what is to be done to avoid the danger of being falsely accused of not having gained consent, other than to simply abstain?
If consent can be retracted after the act, the act is not safe. So abstinence is the only answer.
And really, this shift towards abstinence is an appropriate social response.
The point is, this is precisely the kind of confusion to avoid by maintaining abstinence as your primary mindset.
It is the only way to be sure: abstain at all costs, even if you were given consent, because that consent is not immutable.
You responded to a message which mentioned changing one's mind in terms of continuous consent, not false rape accusations. These are different things. If you want to talk about false rape accusations, don't call it "change of mind".
And that is the point - you're already in the danger zone if you've started and consent has been retracted. Better to just abstain entirely and not engage in sexual activity, at all, under those conditions.
No means no, always. To protect yourself from the "yes .. yes .. okay, no" dilemma .. just say no to casual, irresponsible sex - in the first place.
It is only way to be sure you won't get accused of assault, and even then, if you're not checking for continued consent every few milliseconds while engaged in the act, you're probably having very, very dangerous sex ... so just don't bother.
Why protect yourself? Why is this a dilemma? If you stop when asked, it's not an assault.
If you're worried about this, you're worried about false rape accusations, not some dilemma about people changing their mind. "if you're not checking for continued consent every few milliseconds" is an imagined problem taken to extreme. People who actually change their mind during sex will tell you about it and not treat it as assault.
Ignorance of this fact doesn't support your argument.
Both of these things are relevant in the discussion of consensual sex, and I disagree with your attempt to elevate one position over the other.
Rape is bad because it negates a persons agency over themselves and denies them their basic human rights - false rape accusations also deny a person their basic agency and human rights.
Best way to avoid either case: just don't have sex, i.e. learn the value of abstinence.
It’s important to see how prone to abuse is a new law that will be introduced.
However, I will be teaching my teenage boys that "Yes is not always Yes, it can be changed", and that "No thanks, I'll abstain, even if you give me explicit consent" is always the safest approach.
I’ve seen some people post things like this on Facebook and not realise how crazy it is.
Fundamentally, sex requires trust and analog communication over a connection either physical or verbal.
Of course, in practice people deal with certainly below absolute. But once you admit that, the argument for absolute abstinence loses some of its punch.
So, a new era of abstinence is ahead of us. There is simply no other way for anyone to feel safe than to simply abstain.
Personally I'm okay with this, but I know a lot of teenagers who grew up thinking sex is an important facet of their identity who will disagree...
Frankly, though, I think a more conservative society which treats sex with a lot more respect than the current shit-show, is definitely in order.
