Getting Pregnant on Purpose?

If you have ever driven in a car during a long trip with kids in the backseat eventually the fighting starts. "She started it" as the other cries "stop looking at me, mom she is looking at me." So, you ask the other one to stop looking and the next screaming you hear is "she pointed at me!" They point fingers back and forth and finally you have to tell them to sit as close to the opposite doors as they can, hands folded and look out the window with mouths closed.
I recently was reading a blog when someone leaves this message about how some women get pregnant on purpose to trap the man.
I equate this to any living person that is stupid enough to show up to a judge after being cited for accident involving alcohol. Did the alcohol trap you?
Nobody traps anybody, but you can get caught up in a web of lies. Life is sexually transmitted. All birth control has a failure rate, even in rare cases of sterilization. Where is the surprise when that happens? Maybe we assume that everyone is a mind reader? I think if someone gets a disease from a person and that person did not disclose it, than we have someone that should be hung from the highest tree. How dare anyone ruin someone's health over their own greedy sexual urges, however we can assume that most men and women that are walking around have functioning eggs and sperm that it is their biological duty to find each other. You have agreed to a possible pregnancy when you combine body parts, end of story. You knew you were mixing gasoline with matches from the start, no one did this to you.
It is the same childish phrase about who started it when it really doesn't matter when you both technically agreed to a possible pregnancy when you combine body parts, no matter what the verbal story was, biology does not have ears. Maybe blame the sperm, afterall they always did like her best?
What is even worse is the child that was born out of the lethal "trap of the vagina" gets to live with two parents that really did not want to be in the business of parenting. I understand that people feel like they "need" this and this is nature, but let me remind you that "anger" is also a natural feeling but you can't go bashing peoples heads in because "nature calls." We have brains and two hands (animals have paws) and really any urge you have can be taken care of without reckless disregard for biology. Even when driving a car, you maybe traveling in one that swerves a little to the left, but you should know how to operate the vehicle to protect yourself and others.
Two things that really irk me is that women jump on other women for this and that both sexes do not take responsibility for irresponsible use of their body parts. I know some of you will tell me that you can't stop people from having irresponsible sex which is probably addictive from what I have seen in peoples behavior. Is it any different from a drug?
Meanwhile back at home I think we need to stop pointing fingers and no matter what these two active set of genitals need to be parents because they only have this kid for 18 years and if they do a crappy job, we get them for the next 60 in jail.
