I don't think people can easily suspect the people who have STIs. So I don't know by what percent condom use would decline in case of paper abortions, but I'll assume there'll be at least
some reduction. I do understand the need to put some of the onus on the men to take contraception. I'm open to ideas to incentivise (or disincentivise unprotected sex) but forced parenthood isn't that. I still disagree that this is remotely balanced.
I think the campus scenario is kinda extreme but also removes the agency from women. If you're a girl at uni, having unprotected sex, without being on the pill, without using a morning after pill when neither you nor your partner use contraception, despite knowing you'll be disproportionally impacted in the case of an unwanted pregnancy... then you have a large share of the blame here. Again it's shared blame for the failures, she's not the only one to blame it's the guy's fault too. But forced parenthood isn't balancing things out.
On the subject of vasectomy, because it's getting pushed a lot, I get the feeling there's a lack of awareness about the high risks of it being irreversible. According to the NHS it's estimated that the success rate of a vasectomy reversal is:
- 75% if you have your vasectomy reversed within 3 years
- up to 55% after 3 to 8 years
- between 40% and 45% after 9 to 14 years
- 30% after 15 to 19 years
- less than 10% after 20 years

This isn't something you can rationally propose to younger people as a means of contraception. Like you wouldn't push for tying of the fallopian tubes for young women, it's very invasive and tricky to reverse. You wouldn't push for IUD devices either which are quite invasive too, but a preferable option to tying the tubes. Realistically the condom for men and the pill for women are the only ones you can advocate for at the moment and perhaps tie some legal benefits to using them. Finally, as it stands women have a much wider variety of contraception methods than men. Hopefully will be corrected in the future with technological advancements.
