Before you can have any meaningful discussion about feminism, you need to agree to a definition of it. Feminism has been used to cover everything from equal pay to reproductive choice and even combat roles.
I would call myself a feminist in this regard: I love my wife and try to support her both emotionally and financially. If she works, I want her to earn what she is worth - same as anyone else. But I work harder and sacrifice so she may not NEED to work. I support her "femininity". As a nurturer of our children, I leave some parenting situations to her. As more of a masculine disciplinarian, I take on other parenting situations. My role as a husband and father is very much like a shield to my family. I accept my role to place myself - physically, emotionally, and intellectually - between them and any threat. I strongly object to putting women on the front lines in combat - NOT because I see them as inferior, but because I wish to see them revered and protected - precisely because I elevate them.
Abortion robs women of their dignity and humanity by attacking their role as mother of their unborn child. SACRIFICING YOUR CHILD TO PROTECT YOURSELF (especially emotionally) IS THE ANTITHESIS OF PARENTHOOD. Parents with children deal with this every day of their lives - it is our job as parent to put our kids first. Even in cases of rape or incest, the first crime does not justify the second (and I have yet to hear most vocal "feminists" cry out for the rights of unborn women). Abortion is not about choice. Sometimes we are blessed (or burdened) with children we didn't intent or want. But once that life has begun, we are parents, like it or not. And we'd better start acting like it. As the father of an autistic child, I would never think of my son as an inconvenience or an unfortunate burden. It is precisely by those hardships that I get to be a true father. There is a word for that - love.
Men and women are different fundamentally. Our natures come from the design of our creation and cannot be ignored without societal disruption. Women tend towards nurturing, supporting and raising of children. Men tend toward sacrifice, labor, and defense. We see these roles exemplified in traditional marriage and that is the secret to why it has stood the test of time.
Of course these natures do not absolutely dictate behavior or always reflect us as individual persons, so there will be counter-examples and they need not be suppressed. Some women do tend toward labor and defense. Some men are better nurturers than their wives. But these are exceptions and while they should be respected in our culture, they do not form its foundation.
I am a traditional feminist. I love and respect women. I strive to protect women. And I'm also a masculinist... how come we never talk about that? ;)
