At the end of the year we accept Christmas wishes. Although it is indeed a religious feast, it's also a tradition that even people not practicing the religion may follow.
Ramadan is also a religious feast/step, but all the topic was about was wishing a happy period of fasting and is, like Christmas, a celebration time.
I believe that Ramadan is "as big" as Christmas might be in terms of non-muslim people still knowing what feast it is and what it refers to.
I must also admit that I know about Ramadan but did not about "Eid Mubarak" (which after search is the ending feast of the fasting period).
Indeed, seeing the original post using the ortograph "Aid", I though it was about helping some politic prisoner or something of the like.
Also in the same order of idea, if Christmas is tolerated for Christians in our forums, there are not necessarily mentions of all the saints or all the feast around the whole year.
And those doesn't need to be celebrated on our game making forums anyway either.
Best would possibly have been to simply wish the "Eid Mubarak" in the "Happy Ramadan" topic, wouldn't it ?
That kind of have made a lot more sense then a simple "Nuff said" that was the content of your other topic, and just sounded like w/e.
