It's gonna be like most people discussing politics (Option B) aka "Knows nothing but will argue to the death about subjects he barely understands, understanding of the world is childishly simplistic and hopelessly optimistic". But at least it's not (Option A) "Knows politics but will instantly belittle you unless you're as knowledgeable or on the same side, pompous and passive-aggresive".
I don't get why people like discussing politics online, it's never interesting and you're either screamed at, talked down to, ignored or circlejerking if you agree with someone. I take the same stance as I do with religion: No. Thanks.
