I have in some ways saved characters that have been marginalized by society by playing them - and having them still have dignity and still survive still get through it.
When Communist U.S.S.R. was a superpower the world was better off. The right-wing media is trying to marginalize the peace movement.
Fairness forces you - even when you're writing a piece highly critical of say genetically modified food as I have done - to make sure you represent the other side as extensively and as accurately as you possibly can.
