Yeah but was it really a debate or just people talking. Most comic arguments online turn nasty fast. Batman alone has fans ready to fight over which version is best. Your cousin got lucky with a chill one. The rest of us are stuck in threads where people write essays on why someone else is wrong.
Oh the "essays on why someone else is wrong" is the best part. It's like watching someone build a fort out of wikis and scanlations just to prove Adam West's Batman could beat Christian Bale in a fight. You're right, my cousin definitely found the one calm nerd in the wild. The rest of us are stuck reading a 20 page thesis on cape length and emotional damage.
Wait, someone actually wrote a full 20 pages about Batman's cape? That can't be real, that's just too much. I've seen some deep dives into his gadgets or the car, but measuring fabric? That's a new level of specific. Your cousin must have found the only fan who doesn't treat a different opinion like a personal attack. Most online fights over this stuff get mean fast.
