It may depend on the topic. In my interactions it’s generally seemed like nuance is appreciated, with some caveats.

Politics are a thornier subject. Starting from common ground, before moving to the area of disagreement helps. It’s important to know your audience and have some idea of how the community feels. I think my typical instance may have severed ties with the more firebrand instances, which probably limits hostility.

It’s not terribly different from tackling more sensitive subjects in person.
