One succinct definition of “feminism” is,
Feminism: The advocacy of women’s rights on the ground of the equality of the sexes.
The complementary definition of “masculism” is,
Masculism: The advocacy of men’s rights on the ground of the equality of the sexes.
Using the above definitions, masculism and feminism can be seen to be like mirror image twins. They are equally egalitarian; men’s rights advocacy and women’s rights advocacy, with neither group advocating the infringement of the rights of the gender that isn’t their main focus.
It is in these senses of the two words, that I am both a feminist and a masculist at heart and in deed.
In everyday life, we can easily see just how much masculists and feminists are ultimately on the same side, the side of equality of the sexes, rather than the supremacy of one sex or the other. We can see this harmonious complementarity in play, by witnessing masculists and feminists having their frequent, amicable, polite, reasonable, and fruitful dialogues, for example when trading good-hearted banter on Twitter.
It’s like building the Euro tunnel …
Masculism and feminism (as defined above) are just different parts of the same project. They are analogous to the British and French teams that dug the Euro tunnel, starting from different shores, but eventually meeting in the middle, beneath the sea bed.
