Also, as a man, when I am mostly ignored because people are too eager to speak rather than listen, my first assumption is that those people simply suck at meetings. I have the privilege of knowing that it is not discrimination.

But it might as well be. I was discriminated/bullied for quite some time after I joined a company. People assumed I knew nothing and disregarded almost anything I said, and generally didn't even ask me. I was one of the two people in a department. Those people did not suck at meetings/conversations, it was an active discrimination based on their preconceptions. I don't think gender is by far the only discrimination that can happen within the workplace. But yeah, I definitely agree that I will most likely not being discriminated as a man, in the sense that sexist discrimination in tech happens almost exclusively to women.

There is a lot of competition of ideas going on in tech, very little positive feedback, and a lot of talking over people, because this is just how a lot of men are unfortunately. I fully understand why people who are more likely to be prejudiced against would perceive all sort of false signals in there.

I agree. I - like many others - do my best to change the culture overall, to ensure that people who get promotions have fill leading positions are not those kind of people who will reinforce all of this. Also, I did not work in the US startup environment (and I consider myself lucky), which means I might also be missing real experiences on places much worse than the ones I have been in (the loner-tech-bro-genius hacking culture of the Silicon valley is something I greatly despise).
