You really don't have to personally like someone for them to have useful information

The nazi party member Pascual Jordan contributed significantly to quantum physics but it's rarely mentioned because of that association. On the flip side, also the nazis ignored his suggestions for advanced weaponry, to their detriment I would imagine, because he valued jewish scientific contributions and so was considered unreliable politically.

Also consider that you're on hacker news. Hacker ethics, or at least the version I've internalised, include judging people by what they say, not who is saying it (race, gender, and authority are commonly mentioned, but charismacy could also easily fall in that category)

I'm confused about your argument. At first, i didn't contest her cause or beliefs or usefulness of information. And second, I'm talking about how she speaks. I do not have good words to describe it (inflammatory, immature, full of self?). I do not believe this is a bogus criterium in the sense of the hacker ethics.
