Make a genuine case for why someone is the younger brother of Jesus Christ and why that means he should rule over the landmass formerly known as Ch*na. If you're going to dress up in little soldier costumes and have little flags and pretend the ROC is real, you may as well have fun with it.
Taiping were even worse than RoC though
I'm sure they were in some "moral" or "ethical" or "body count" way, but they had fun with it. I look at the ROC and they take it so seriously.
Depend who, like all the seriously serious things after Xinhai revolution, and suddenly there is some clown running around, crowning himself, then another one diggin up the mushroom-like Pu Yi...
