If you're a cis-man and against abortion, you have some responsibilities:

1) Wear contraception when you have sex if you do not wish to cause a pregnancy, or don't have sex(whichever you can manage);

2) if you cause a pregnancy by having sex when not wearing contraception- it is specifically the MAN's responsibility on that point, since the woman is in all cases far more affected by that situation- you have an obligation to either help raise the child or financially provide for it until the child becomes an adult if you cannot, for whatever reason, be a partner in the childraising; these are NOT negotiable points;

3) If you succeed in getting both abortion AND contraception banned, recognize that there will inevitably be a massive increase in unplanned pregnancies, since it is not a reasonable expectation that everyone else will simply not have sex unless they WISH to cause a pregnancy; recognize that, being largely responsible for forcing others into situations they would not have been in had the laws you worked to pass not been passed, you are now personally responsible for helping provide financial, medical, educational and other support to those who are coping with the situations you are significantly responsible for forcing these people into-recognize also that 1) if there's a "right to life", that includes a right to something like a basic standard of housing, education, and possibility in the future of all whose lives you have intervened with- recognize also you have a responsibility not to judge anyone you have imposed on by passing such laws and an obligation to recognize that you are not morally superior to anyone you have imposed on.

It goes to the basic principle that if you have caused anyone else hardship, you yourself are obligated to help alleviate or if possible eliminate the hardship your intervention has caused.
