The key to peace and tranquility is quite simple: For any with the attention span of a squashed gnat I will repeat the opening post:
No personal insults
No dragging up the same points again and again and again
Stay as polite as you can be...
Respect each other, even if your political opinions differ.
No racism, sexism or other isms
Simples! Do not say or even imply I am a racist and I will not have to defend myself. It is that easy!
