It's a fun question to think about really. When religion and tradition have created a primitive patriarchal system, where women are abused, treated as property, and are held to be mere vessels of male shame and pride, men think of their way of life as "The way things are supposed to be".

In such a case, suppose there were women who protested against their status, and the "powers that be" were to have a change of heart, become more enlightened, and move toward equality. The general male population would perceive an attack on their faith, and that threat would be coming from the men in power who are compromising cherished tradition.

But the OP is not even talking about primitive cultures. The question seems to be along the lines of, why do modern men in our own relatively advanced culture perceive women to be a threat? Thousands of paragraphs could be spent in the exploration of "why" men sometimes resist what women would think of as an even playing field, but I just don't think that "threat" is a part of it. An inability to list many other sources of the problem having nothing to do with a perceived threat seems to be a result of not trying very hard.
