In a way, I can empathize with him, but I firmly disagree with many things he wrote there.

You can either be a nice guy who is nice all-around, and no woman will change that fact, or you are nice to impress the girl, which in this case, assuming you "won" her, you might stop being Mr. Nice Guy because you have achieved what you wanted.

If this guy was a nice person and a woman changed that - I pity his lack of character. The strength of a person is to stand by what you believe in regardless of what other people think of it.

The whole point of this letter was to say "women don't know what they want from themselves" and while this might be true for some, it is not true for all. In addition, it goes the other way around as well; the main difference being most girls thinking it is beneath their level to hit on a guy they are interested in, so usually you'd end up seeing Mr. Nice Guy and not Ms. Nice Girl, and that does not mean women in general are not as nice as men.
