"I should have known better. Pro-life arguments are now based on scientific evidence and the pro-choice arguments are not. That is a cultural, historical fact"

This quote by Stanley Fish suggests that the pro-life motion has actually moved its arguments to be based upon scientific evidence, while the pro-choice motion has not. This implies that the pro-life motion has actually become more reputable and convincing in its arguments, while the pro-choice motion has actually not maintained. This could be due to a lack of scientific evidence to support the pro-choice movement, or it might be due to a cultural and historic bias versus the pro-choice motion. Either way, Fish suggests that the pro-life movement has actually become more persuasive and that the pro-choice motion needs to capture up in order to be taken seriously.
