The Catholic Church is a liberal outlier. It’s so far away from the median that many if not most Christian sects do not consider it as “Christian”. One major difference is that Catholicism acknowledges evolution as a truth so it’s no surprise that they consider us as heretics.

For context, I was raised as a Catholic, had well over a decade of theological study (including university level classes), and I’ve had significant contact and relationships with other Christians in the Southern US.

Most religious people do not have the privilege to attend a more intellectual leaning parochial school. Weekly 30 min sermons are not enough, but that is the norm for most religious people.
