Also, I'm female, but I don't really agree with the article from the OP at all. For one, I don't feel all that enamored with the institution of marriage, secondly, religion isn't for everyone, and doesn't equate success as a person in the slightest. Lastly, what was discussed there were simply more sexist gender roles, this time against men. It's just the same as women, pressure to be one thing or another.
True, women are a subordinated group in many regions, including the United States, but there's no reason why that means that men don't also experience limitations and oppression because of their dominant status - people just generally don't see the similarities between the experiences of the two, and focus on what women have experienced. I agree that there should be more light shed on what women go through - the fact that 1 in 4 women will endure sexual assault/rape in their lifetime is testament to this, but articles like this also shed light onto the pressures and gender roles that we place on men.
No matter your gender (or if you prefer to be gender neutral, whatever), you shouldn't be expected to adhere to one role or another, or be subjected to societal pressure to, say, marry. I don't care who you are, you should be free to be your own person - not to feel like you're "in danger" because you haven't met someone else's shoddy standards.
Thus, if I were ever to call myself a feminist, it would be bearing in mind this definition, the usual definition, actually:
Feminism is a collection of movements aimed at defining, establishing, and defending equal political, economic, and social rights and equal opportunities for women. Its concepts overlap with those of women's rights. Feminism is mainly focused on women's issues, but because feminism seeks gender equality, some feminists argue that men's liberation is therefore a necessary part of feminism, and that men are also harmed by sexism and gender roles.
