For myself, I generally try not to have an opinion on almost any controversial issue.
Many issues that are now relatively uncontroversial where once controversial, or are still controversial in other parts of the world. Do you also suspend judgment about such issues? Is your reference class the roughly 100 billion people that have ever lived?
That depends on if I think modern / first-world society has significant reason to claim epistemic superiority over their past / third-world counterparts. In most areas of thought there's a concept of progress and building on the accomplishments of the past, and to a very large degree the experts that benefited the most from that progress are concentrated in first-world countries.
For every controversial subject I've heard of, there are always numerous very smart experts on either side. So I'm curious how it is that rational non-experts come to believe one side or the other.
So, what are your meta-arguments for going with one side or the other for any given controversial subject on which you have an opinion?
