Why do women hate shy men?

Answer

To say that all women hate shy men is a very sweeping statement. Most likely, sometimes women ignore shy men because those men, because of their shyness, don't speak up and say something interesting. People (either men or women) might also observe a shy person and think that person is stuck up because he or she doesn't join in conversations.

You might start by treating a woman like any fellow earthling--comment on the weather, the traffic, the local sports team, the new coffee option at the corner goodies bar. Then figure out what she is interested in, and talk about those things.
