Who defines what beliefs are odious? The point is not to convince the person you are talking to, which is very difficult given how much people stick to their political beliefs, but to convince the lurking third party, who has weakly held opinions. If they can see in the debate that one person has the stronger argument, you can convince that third person. If they see one side refuse to debate, angrily yell, and banish the other to places like the_donald, well, maybe the undecided lurkers will wonder if perhaps the person got angry because they had no good counter-argument, decide to go explore a place like the_donald, or some other echo chamber where they just become more convinced, that also has no counter-acting voices of reason. The people in the_donald agree with you by the way, and don't give space or respect to people with odious blue tribe beliefs. Sunlight is the best disinfectant.
