Let me say this, then: With your definitions, you are "proving" things that are false. Example:
Looking at the situation from dispassionate neutrality. the timid wallflower player (Timmy) can be just as disruptive to overall play as the aggressive jerk player (Aggie). Every time it is Timmy's turn he takes forever to decide what to do and then always ends up doing something lame.
A quiet and timid player is not always the player that takes forever and decides to do something lame. That's a false dichotomy and it's bullshit. My group has one player who is quiet and timid, but he generally knew what to do (granted his character was a charger, so he charged a lot). We also had 2(down to 1 now) guys who were loud and obnoxious and were not only generally
not interested in the game a lot of the time, but also took forever to decide what to do and then always ended up doing something lame.
You do this constantly. You start with saying something like "People who are disinterested in the game are disruptive," but then you move on to say that "all people who are shy are disinterested in the game and suck at it."
Also you often define things in an unfairly broad manner and then don't appreciate the fact that your definition isn't functional. For example: "It is never okay to kick someone for in-game reasons." You define In-Game reasons as things that occur In-Game. That does not address the situation, it doesn't help to clarify jack shit... it's a worthless definition. You also refuse to accept that In-Game stuff does not disappear the instant the DM says "see you next session." There is no In-Game and Out-of-Game, there are only problems.
