I think we shouldn't - Countries are different for a reason. It is because people of different origin live in those who don't share the same mentallity. You shouldn't try to enforce your own morals on others, and let others do as they wish. By trying to combine countries into one and trying to force your morals on other communities you help no one.
This is something from the US, and should be kept to the US.
Much better would be to hide the display on a global site, what is the point of me seeing the display. Do I have to site in my chair grasping for air thinking "oh no, those poor people overseas"? I can't do anything else.
EDIT: explain the downvote, I'm really wondering what's the point of displaying it to me when I can't do anything? - I'm really getting annoyed with this, do the people of the US think of themselves so high that they simply can't stand others saying "it's not important for me at all"? There are many countries (looking at you china) who have much worse laws, and getting worse day by day. Why dont'we put a permanent banner there?
You expect me to do anything about it? Well I told my premier (comparable to the persident) to not go to the olympic plays at china as they didn't allow for an open internet. What influence did that have?
