Legal abortion will never stop so long as women think they are morally excused, and I for one, will not provide them with that excuse. My position on this is non negotiable.
Other than that, you do what you think is right, and compromise, what you think you need to. Personally in the end, I think you're making a deal with the devil...
You are ALONE in your arguments, pretty much.
I would also say that you come off as a bit misogynistic, a bit anti-woman, a bit like the very WRONG stereotype of the left tries to use, against us.
There is no legal, logical, moral or historical reason why we should be compelled to treat the mothers who have illegal abortions harshly, with prison or with jail time.
