Love one another, it is in their own holy book and so many don't do it....
Never use all inclusive terms. Such as, "All men/women are this way", or "all muslims are terrorists" etc. All inclusive phrases are inherently wrong and divisive.
Avoid biases and stay objective to the best of your ability. Recognize on a fundamental level that you don't live in a vacuum and that your choices impact others just as much as theirs affect you.
We are a bunch of self entitled apes on a big floating ball (ish), trying to figure out how to get along with eachother.
@WizardBill Good points. haha
The concept of being able to change your mind, as if it were your direction in a dance.
To subject any evidence or arguments that you are presented with, to the most severe amount of scrutiny and ridicule that you possible can. Any evidence or argument that stands up the best scrutiny/ridcule means that it is probably true, any evidence/argument that does not stand up to scrutiny/ridicule is probably untrue.
This rely's on people caring about the truth as apposed to what they would want the truth to be. The impact this would have is onvious. We would have a society that constantly explores ways to improve/enhance our lives, for the benefit of all
