My "favorite" edition war exchanges usually go like this:
A: [Incorrect statement about edition X.]
B: Actually [what actually happens, or what the rules actually say.]
A: [Repeats incorrect statement about edition X.]
B: As I mentioned before, [what actually happens, or what the rules actually say.]
A: [Silence.]
...
Some time later, in another thread:
A: [Exact same incorrect statement about edition X.]
B: Look, I'm not going to bother repeating myself again. Here's a link to our previous conversation on the issue.
C: [Also makes same incorrect statement about edition X.]
D: [Quotes A and C, agrees with them.]
E: [Gives XP to A, C and D, with the comment "+1".]
B: You know what, I've started another thread to explain the issue. Here's a link.

Some time later, in yet another thread:
F: [Same incorrect statement about edition X.]
G: [Quotes, F, agrees with him.]
B: Here. Link. Read.
H: [Gives XP to F and G, with the comment "+1".]
