Actually sometimes the pro choice is about pro abortion. I was bullied by a doctor when I was pregnant at 17 as he said I was too young, I was bullied when I went to the Brook for a pregnancy test back in the day when you couldn't buy tests, they said as I had a young baby I should have an abortion.
Then when I was pregnant at 38 and politely turned down the triple test the doctor got very annoyed as it needed to be done quickly as we were running out of time for amnio and then abortion if needed. He got really angry and the midwife had to intervene and tell him to stop and that my Consultant had discussed it with me (calmly I might add) and I wasn't having it.
So I'm not entirely convinced that all pro choice is as kind and supportive as people think.
I think you can get people being unpleasant at both extremes.
