Nerds are a hard to define group of persons. Depending on the kind of group of people, nerds have different properties. In some context it is used as a term of honor, while other use the term to decry someone. In the article I assume to a different definition of nerd is referred to. A nerd is there a person with low self-esteem. Someone who thinks suppressed, mobbed or ignored by others. They are a little closer to the autistic side and they feel uncomfortable around other people. Even more when those people are not nerds too.
The male version of such nerds tend to have had not much experience with women and might not know how to act proper around them. They might be even aware of this fact. They might even understand the psychology of mating rituals, but as they lack the intuition (which comes from practice and success) they have an unsatisfied need in that context.
A mental solution to fix this from a personal point of view is to imitate successful role models. These figures can come from the real world or from TV, books, videos and even games. However, these role models are mostly incompatible with the present and often not compatible with any culture on earth to any given time. Nevertheless, they often carry an image of women as "bitches" or "slaves", which can result in a male behavior which is highly inappropriate.
Another solution from a personal view is projection of self-hate onto others. Example: From "I hate me for not having sex with women" the nerd makes the switch to "I hate women for rejecting me". This even works when he was not actively rejected but ignored.
Both strategies can even used together for a maximum of awkwardness and hate.
Please do not misinterpret this as "He hates nerds". I don't. I am one myself. Even though I chose a third solution and after decades I tried a fourth that worked and now I am a normal person ;-)
The third solution is suggesting to yourself that you are not interested in women beside being a friend. I tried that from 20 to 35, which worked perfectly in the beginning because I had my first girlfriend shortly after I switched to that scheme. However, that relationship only worked for some month and was totally unsatisfactorily for the next 15 years. Then I decided that a new scheme might work even better. I could try to be polite and ask women out, but first I should not look like an unwashed yeti from under the bridge. And that really worked. It would also work with people who have chosen method one or two. However, they need first to accept who they are and then accept that women are humans and equals. And acceptance is not achieved by saying it but by meaning it. If you have any trouble with that: See a shrink. I did (somehow). It worked.
