Are you a feminest by any chance? I am all for the rights of woman, and no, masculine qualities are not needed to be strong.
Some people just dont like feminine names. Some are not "girly" or have more boyish names, or feminine names that like more boyish nicknames. Just because you like feminine names on girls does not mean everyone does, or even that everyone should. I dont expect people to like my names, or the nicknames I like with those names, or even my style. Its not my problem.
