I'm pretty sure that a poll taken of most Catholics would show that they think abortion and birth control are moral. I'm also pretty sure that a poll taken of most Catholics would show that (to the extent they've heard of the issue at all) they think the medieval Church was completely wrong in how it treated Galileo, not just factually wrong about heliocentricism.

The church itself would disagree. Is it illegitimate to crticize either the church or Catholicism on that basis?
