I find that it's easier to understand people when they utilize the logical side of their brain, setting aside the emotions for proper discourse that others could potentially learn from.

Emotions running one's mouth will shift a possibly smart discussion topic into weird directions.

Slinging insults at people to get a point across while also failing to discuss the matter with people of differing opinions is asinine. Generalizing people into a group for an opinion because of a disagreement with that opinion is an emotional discharge at best and fails to bring any meaningful insight to the table.

People sometimes need a nudge to use logic more often around here.
