So there’s a big whole complex of online harassment, offline harassment, misogynistic attitudes, beliefs about dating, “strategies” for “getting” women to date or have sex with you, weird money related ideas about all of this, ideas about strategies to turn a no into a yes, etc etc, that is in the background whenever normal low stakes human interactions are happening. So it’s not the act of saying “hi, you seem cool, let’s get coffee” that is the problem. It’s the context. Tinder is making the context so, so much worse. It’s creating creating conditions that make an otherwise normal ‘hi’ seem more likely to be in bad faith, and sending a signal to malicious people that a new option for being malicious has opened up. So, even if the vast majority of people looking to meet humans this way are totally kind and earnest, it brings a certain vibe to the entire thing that will make many people, especially women who have had scary or unpleasant experiences in that vein, very uncomfortable, and cause them to think twice about that “hi”, because they know that access to their inbox has been sold, when that was never allowed before, to people who may be more likely to have bought into the aforementioned complex of bad ideas. It makes the “hi” not normal anymore.
