What if the facts or basic-ness of them are disputed?

You can see this clearly in pro-choice/life debate for example.

One side is saying it is murder and the other side is saying everything from it is not a murder to society doesn’t support the born kids, so this should be allowed.

What are the ‘basic facts’ here?

The side that believes it is murder also trusts the bible, just point them to the ordeal of the bitter water: https://en.m.wikipedia.org/wiki/Ordeal_of_the_bitter_water

Though hopefully they won't get ideas to make it involuntary again.

What ends up happening in that case is that people disagree in defining "What is a human?". That's not about facts, it's about values and conclusions. That becomes uncomfortable very quickly, because we've seen what happens when a society excludes some people from their definition of humanity.
