Here's the thing ... I understand your point but we have two votes.
One with attached reasoning.
One without.
The first can be analyzed for such things as scum intent and how said reasoning melds with other posts by the player.
The second cannot.
While we seem to be on opposite sides of the spectrum as to thinking explanation is a Pro-Town action it is easier for scum to hide their pushes under the second kind of vote and say "I thought it was obvious, draw your own conclusions". Town can do it also but that only enables scum to do the same.
