as before, posting my response here because I’ve handed off my reddit account to a friend so I can’t keep trying to fix the internet. I’ll re-post to reddit when I get access again in a week.
In response to “he said she said” comment, as replicated below:

I’m sure an arrest would satisfy your desire for truth [/sarcasm].
The fact that there are laws against something is evidence that it happens (so we make a law against it, e.g. no one is seriously making laws against murdering unicorns), not that it doesn’t happen. For instance, there’s laws against speeding and jaywalking, and they definitely still happen. Another example, rape is illegal and people do get arrested for rape, yet people still doubt it happens. Therefore, nothing you read on the internet will convince you, especially if you start from “everyone is lying to me / people are all liars” and the thought is on the tip of your tongue ready to leap out the second you read something contrary to your beliefs.
So seriously, just go talk to people in real life—everyone will be much happier, you and I included. In real life, you will have to look people in face and stare them in the eye and deal with the fact that you could end up feeling sh***y about yourself when you call your friends a liar to their face.
I tell my friends in real life when they are being wittingly or unwittingly sexist, and I feel sh***y as f**k all when I do so. But I deal with it, I deal with their anger and resentment and backlash, I deal with them saying “bulls**t” to my face, I deal with them saying “I’m too busy dealing with my own life and issues to listen to you”, I deal with them saying “I only care about hardcore technical issues and I’m proud of that”, I accept they will tell me “I don’t care about your pet cause, stop talking about it”, I listen to why they are feeling the way they do—I do all this so that we can grow together, and because I’m a grown-up woman and I’m their friend. Because I accept that, if I want them to listen to me, I need to listen to them too.
I listen to them, because I know what it feels like to not be listened to.
I’m far from perfect at listening instead of reacting in anger, because I’m human. But at least I try.
I’m challenging you to do the same. Get off the internet and go talk to people in person. Woman up, like I did, and confront them in real life. Engage with people in order to grow your empathy and understanding of why other people believe what they do, instead of trying to prove to yourself what you already believe. And don’t sleep easy until you do.
It will take effort and time away from honing your technical skills. You will have to be comfortable with being uncomfortable and distressed. You will have to accept people’s anger and distrust and hurt and discomfort and apathy and backlash at you. You will have to work to seek out opposing opinions instead of shutting them down. You will have to work to gracefully accept criticism when you inevitably get angry, fail at listening, and fail to hold yourself up to your own standards.You will have to acknowledge the limitations of statistics and the limitations of your knowledge—you will have to put all your opinions aside so that you can fully be there when your friend is asking you to listen to her. You will have to work to broaden your circle of real friends, not just token friends, so that you can talk to people with diverse life experiences with whom you have a history of doing things for in return, instead of just demanding their knowledge and opinion and attention in a one-way relationship—you will have to ask for their trust in you, instead of asking them to lay their painful life stories before your skeptical eyes for you to tear apart while you call them liars “who have zero issue lying” and give them no trust nor respect in return.
And this is the effort you have to put in to be a grown-up woman.
