Our high school programming teacher was a math teacher who knew to keep the kids in the back -- the ones who finished reading the textbook in the first hour or so of class -- completely alone. We didn't cause trouble, and we were quite helpful to the other students in the labs. At one point we were asked, politely, to stop crashing the county's mainframe (which was the platform we were using). So we stopped. Girls? I don't recall girls. They must have been there; I don't think we noticed. We certainly didn't harass them, and we probably tried to help them. We were geeks and tools and had no idea how to interact with 'em, for the most part. The OP's story saddens me.
