A united symbol for non-Islamists

There is a great need for a universally known and recognized symbols for those non-Muslims Muslims who prefer Civilization and therefore want Sharia to be as weak as possible.

The reason is that symbols has great powers over the mind and heart of humans.

A symbol of this kind is necessary to strengthen the movement for Civilization. The arguments are the same as those presented in the earlier blog post "Visibility of personal ideology".

What would a suitable symbol be?
A sun? A benefit is that the sun like the moon is a stellar unit (Islam has the moon as symbol). The sun represents lots of light, the moon represents a sometimes small portion of light during night, which accurately represents Civlization vs Sharia (light vs darkness).
