Let's post some reasons or evidence why one would type themselves or another person wrongly. Try to make them legitimate, so we can comprise a list. Let's also discuss which reasons or evidence is not legitimate. Take this piece of evidence for example, is it legitimate?
One typed claims that they don't really like their dual types in the past. How probable is that? How easily could you say that person mistyped themselves, their socalled dual, or both, wrongly? I often see the P/J switch, then all of a sudden it's clear to them why they didn't get along with their dual, because now they're socalled conflictors. But how probable is it that they're still being mistyped, even on both ends? Is a simple P/J switch all that convenient?
Anyway, I apologize for all the rhetoric. That is just one circumstance.
