Fair enough, but if this hypothetical character is not interested in people at all, I don't see why he cares about the gender distribution of people who share his interests. The implication seems to be that this person is interested in social contact, and uses his other interests as a filter to decide who he spends time with. My suggestion was that the desire for social contact might be more effectively satisfied if the person trained himself to be able to talk about (and at least temporarily be interested in learning about) things that he isn't immediately interested in.

I wouldn't characterize myself as merely being interested in people, incidentally, because my desire to converse with other people about their interests isn't indiscriminate. I doubt I could sustain an interesting conversation with someone who is really into the life and work of Kim Kardashian, for instance.

I was hoping your reply was the 'more pointed summary' I intended to post, but since it's not:

.. Being interested in how people work and universal human experiences.
