This question is not just about abortion but also any other freedom that considerably affects specific groups' well-being, health, or safety.
If you are a conservative, liberal, or otherwise and you oppose, say, the legalization of elective abortion, right to proselytize or openly practice one's religion (which is banned in some countries, such as Saudi Arabia, for all but the majority religion), or same-sex marriage, how do you square that with having friends who may be negatively affected by such legislation?
For example, I have conservative friends who have told me that knowing me has changed their views on apostasy: whereas they previously believed that apostates should face capital punishment, knowing one on a personal level has added a layer to their views on the issue that they didn't consider before. They changed their mind when the issue no longer became a mere distant abstraction to them.
So, if you support or oppose certain things such as the above and know someone who falls into a category of people who will be affected by them, do you take into consideration the effects of said views or a vote based on them on your friend, acquaintance, etc.? How do you address the knowledge that they may be harmed by something you endorse?
