This is an interesting tidbit I got from speaking with my buddy from work Tyhm the Philosopher (my title for him, not his).
He has come up with an analogy that demonstrates the no matter how close in fandom people are, nerds will always find something to argue about.
It goes as follows (as best I can remember, some may be re-worded with my speech pattern):
"They have a sci-fi convention in Plato, Texas.
At this convention, fandoms will divide into sections. Star Wars, Battlestar Gallactica, Farscape, Star Trek, etc.
The Star Trek fans will then divide by series. Original Trek, Next Generation, Voyager, Deep Space Nine, the reboot.
Original Trek fans will then divide into which character they like. Kirk, Spock, McCoy, Uhura, etc.
The two Spock fans in the room will then argue about which set of ears Spock had were better. When they were made from real rubber or synthetic latex.
This proves no matter what, nerds will always find something to argue about.”
I wholeheartedly agree.
