Hacker culture is inherently antiauthoritarian, therefore queer and leftist. If you have a problem with queer leftists in your hacker community, you are the problem and need to leave.
I don't doubt that queer and leftist people gravitate towards hacker culture, but how does queer and leftist follow from antiauthoritarian? The majority of people are still, and will always be non-queer, and a significant portion of antiauthoritarians are not leftist.
