Where's the line on this, though?
For a lot of people, opposition to abortion and gay rights, and enforcing traditional gender roles are part of their religious beliefs, whether Christian, Muslim, Jewish, Hindu, etc. Either a critical view of these is off limits, or you create a fictional world where you give a skewed perspective of religion by avoiding having any of your characters (or worse, you only have bad guys hold those positions) hold these not-uncommon positions within their belief systems.
