So, this scenario isn't exactly uncommon in the startup world. It happens all the time. But because she's a minority female and her competitor is a white man, it suddenly becomes an example of white supremacy and the patriarchy conspiring to oppress her. The VCs who funded the competitor? Obviously racists and sexists, and she called them out explicitly as that on Twitter.
I considered reaching out to her to offer some perspective, but ultimately demurred. Why? I didn't want to be caught in the wurlitzer. Better to let her make more problems for herself than offer a sense of perspective that could get me cancelled.
I can't pretend to have any idea what that's like. However, I do know what it's like from the other side, wondering whether the things I say will be misconstrued as prejudice and whether any bad experience I have with someone of a difference race/sex/etc will be used to label me as a bigot.
I don't think I ever thought differently of anyone for their sex or skin color as a kid. Now I'm so worried about offending people that I force myself to be hyper-aware of anyone with those kinds of traits that differ from my own. Maybe it's easy for me to say from my position, but I'm not sure how we'll ever come together so long as we keep highlighting those sorts of differences.
I do not have these sorts of worries around people with whom I am well acquainted. I know I'm not prejudice and I trust my friends to interpret my words and actions in good faith. But I recognize there is a minority of people out there who will intentionally take what I say or do in bad faith if it benefits them. People like that exist in all groups, regardless of physical traits. When interacting with a minority or protected class, I have to worry just as much about interpretations of those around me as that of the person I'm interacting with. In a world where accusations of prejudice are often met with a guilty-until-proven-innocent mentality, any such accusation is very damaging regardless of who it comes from.
