Why Do Many People Not Understand Accountability & Responsibility Regarding Reproduction?

There's a perception that conservatives have to choose between supporting abortion or supporting social welfare programs to support children that some people aren't fit to parent or afford.

What's wrong with people avoiding pregnancy if they're not financially, emotionally, or mentally ready for the responsibilities of providing for kids conceived through legal intercourse? Adoption is also an option. I think the responsibility of preventing unwanted pregnancies lies predominantly with females since there are many more medications and devices available to them to prevent pregnancy and they are the ones that would have to carry it to delivery.

I also think it's inappropriate that a female, including minors, can decide to abort a fetus conceived through consensual sex without input from the father. Men don't have the choice to forfeit their financial responsibility unilaterally, but it's currently acceptable for the mom-to-be to forfeit her custodial, financial, and parental responsibilities for a fetus that took two people to create.

It's irrational that some of these people that think pro-lifers should support children that would have been aborted don't think that pro Middle Eastern refugees, pro central and south American asylum seekers, or pro illegal immigrants supporters should fully and independently fund those "humanitarian" efforts.

It's also irrational that some of these people rant about gender inequality when females have vastly superior rights or advantages in abortion, custodial disputes, marriage, and divorce along with other areas.
