No, they shouldn't be able to. Nor should women be allowed to choose abortion on the grounds that they 'don't want a baby'. I'm opposed to abortion. However, I do think a woman whose life is on the line, should have that choice.
That said, it's a simple concept. You shouldn't be having sex until you're ready for a baby, whether that be 16, 26, 36 or 46. It does not matter in my book.
Yes, I do think that a man should have the choice to request his partner to not have an abortion, if the sex was consensual. It is his baby, too. As another person said, if women alone have the right to decide whether to abort or not, a man alone should have the right to decide whether he's going to support that child or not. I think very lowly of men who run from their responsibilities. And, I apologize to any woman who has had an abortion, but that sickens me. I am unable to have children, and would gladly give one a loving home.
*I don't feel that omorris' comment about the 'timing of a pregnancy' is valid. Again, considering that a pregnancy can be prevented simply by refraining from sex, I don't think timing plays an issue.*
*I look at it like this, as well. Only the woman can choose to have an abortion or not?. Well, the woman chose to have sex, thus choosing to have a baby, irregardless of whether or not that choice was a conscious one. A woman also cannot get pregnant without a man (or at least without sperm); therefore, how can she, and she alone, have the right to make this decision?*
To the OP: I'm not a humanist. I'm staunchly pro-life. As far as I'm concerned, this feministic choice to abort is one of the worse things to happen in North America. I'll bet someone back then said "You wait and see! It'll become a form of birth control" and the feminists pushing it said "No, only for cases of rape or incest." Makes me laugh. There's usually a bigger agenda.
*I agree with vianka, as well. If a man were to have the right to force his partner to carry the baby to term, he should be ready to accept 100% responsibility for the child. The mother should also have her parental rights terminated, allowing for the man to have complete say in the child's life.*
Edit: Again I have something to say about sex, in response to another comment that's been made. Yes, sex is great! I agree, 100%. Sex is good. Yes, again, 100%. But sex is not some 'game' that you should be trifling with. It is an act which causes pregnancy, and an act which may spread disease. 'Responsible' sex is only truly responsible when you abstain from it, or when you are having sex with only ONE person, whom you know is free of all STDs, and with whom you would be willing to share the responsibility of a child with. Abstinence is NOT that difficult. I refrained for 22 years until I had an engagement ring on my finger, and I CAN'T EVEN GET PREGNANT! I have no reason to abstain, except for the STD issue, but yet I did. There are far too many unwanted children in this world, and far too many in foster care because of parents who are completely irresponsible. When my husband and I attended an adoption orientation, we were told there was a girl well-know to Social Services who was on her 12th child, and every single one of them was in foster care because she was a cocaine addicted, alcohol-abusing prostitute who used to take her 'clients' while her oldest baby was sleeping on a urine-stained mattress right next to her. She told the social worker that she was going to continue having babies until they finally let her keep one! How sick is that?!
There are also far too many abortions because our young girls are being taught that it's 'just a piece of tissue' they're having sucked out of their bodies. Ask any woman who regrets her decision to abort, and she will tell you the heartache that she's suffered because of what she's done, and the lies that were told to her so that she would choose the (very profitable, I might add) option of abortion.
I truly believe part of the problem is that we are look down upon younger girls getting pregnant in the first place, causing them to be afraid of telling their parents that they're pregnant. If I had a daughter who came to me at 15 and said "Mom, I'm pregnant", I would not judge her. I would be disappointed that she chose to even have sex at that young age, but I would love her, and help her do what she needs to do to take responsibility for that child. It is NOT that uncommon to be having children in your teens, and considering that's the prime time for a woman to be fertile, perhaps that is what nature intended. My mother had a baby at 18 (me). My aunts all were married and had begun their families by that time. In fact, my oldest aunt was pregnant with her first child while my grandmother was pregnant with her last. Are we really so arrogant to believe that we are THAT enlightened because so much has changed in the past 50 years?
