First, pregnancy also carries real medical. I have no doubt that Lursa will bring that up, if she hasn't already. According to some, more risk than an abortion. I am not sure I buy that. Different risks to be sure, but I'm not sure we can objectively say one is more or less risky than the other.
That said, this paragraph is either a strawman or a red herring, since the OP's premise does nothing to remove a woman's right to an abortion.
You're absolutely correct that pregnancy carries risk. Case and point, women have a right to evaluate and mitigate risks to their own bodies as they see fit.
It's not a strawman, you are simply not understanding. A big part of this male-opt out notion revolves around giving a woman "enough time" so she can decide if she wants an abortion or not, in lieu of knowing that she won't have support from the father. That is effectively leveraging her to have an abortion if she does not want to live a post-partum life of destitution. In other words, it focuses solely on the woman... either as punishment, an attempt to correct a natural reproductive power imbalance, etc. (I am seeing multiple motivations here, some of them sinister.)
It's not a woman's fault that she has a uterus and that that is the default location of a pregnancy. It's not a matter of her saying "Haha I have all the power!", it's more like, "****, the baby is in here, what am I going to do?"
Out of curiosity would you allow for a man to divest himself of parental responsibilities if he was the male victim of a female rapist? Or if it was shown that she aquired semen from him against his wishes, such as getting a used condom of his that he used on another woman?
I won't be drawn into a hypothetical scenario, especially one so rare as to be practically irrelevant.
By the way, semen doesn't work that way. Sperm are extremely fragile. They die rather fast outside of the body, on contact with anything that isn't the vaginal wall. Chemical or temperature change kills them within minutes. So the whole myth of fetching a used condom from the garbage and using it for insemination is another urban legend perpetuated by the same MRA fanatics who don't have a leg to stand on.
I feel that the underlying issue here is actually to do more with needed reforms in the family courts, and with the rot that lies at the heart of the modern relationship between men and women. So much objectification, so little transparent and honest communication, so little integrity. People are getting more and more stupid with each passing year. The whole opt-out discussion, and the abortion debate itself, are the most downstream consequence of an utterly corrupt and dysfunctional relationship between the men and women in society.
There is so much broken trust that men are turning to nanny government now to try and leverage women into having abortions so that they don't have to pay child support as a consequence for a sexual act that they willingly took part in. Maybe this is my Christian upbringing talking, but sex carries responsibility. You should know better. This is the year 2019, most men get a basic sex education, which includes pertinent knowledge that no amount of "safe sex" is a 100% guarantee against pregnancy. Biology is what it is. Women gestate the offspring and have more power of choice over what to do with it. Men have very little agency once their sperm is given... and I don't think twisting the arm of the legal / family court system is the way to correct that.
It doesn't seem moral because it doesn't coincide with the natural balance of reproductive power. You can't give men the same choice to opt out that women have because it doesn't play out the same way. It will cause suffering to women and children and is actually another form of imposing anti-choice, not much different than banning abortions. If a woman is poor enough, then she is going to be cornered into getting an abortion if the father financially abandons her.
The opt-out proposition is inequitable.
