A book published by a former men's rights activist back in 2001 and written throughout the 1990s. It's a bit outdated, but overall, I found it to be quite interesting and covering many different topics. Thought it would be a welcome addition of information. Since trigger warnings seem to be mandatory, I'll mention that the work is a rather provocative one.
