What does the writer mean in this paragraph?
Here is the paragraph
"When it comes to being attractive to women, internal insurance is unnecessary as women do not care why men are confident. They only care about the external appearance of certainty, how males behave, because that is the only thing they can see, and it has proved to be a good indicator throughout the history of our species in the selection of suitable sexual partners[...]
Since most males also believe they have to feel certain on the inside to be confident with women and because most of them believe that women want plenty of things that they do not have, they are likely to lack confidence around women and feel inadequate to get them. Meanwhile, they will prioritize success in society to feel certain that a female would be interested in them, and they will postpone the pursuit of women until they feel worthy, expecting that there will be such a day."
Why does the writer say "Since most males ... confident with women"? is "feel certain on the inside" not good ?
