Singapore, being a multicultural society, has had its share of cultural conflicts. These misunderstandings used to pervade entire communities, but now people are generally more respectful towards each other's cultural practices, thus avoiding the occurence of large-scale conflicts.
The absence of major conflicts does not mean that we can be complacent and pay little heed to etiquette when interacting with other. I find the following minor (albeit slightly unpleasant) incident to be rather telling.
A group of friends, inclusive of people of various races and religions, were having a meal.
Wayne* (to Aishah*, a Muslim): Y'know, I think you'll look better if you trim your eyebrows.
Aishah: My religion doesn't allow me to do so.
Wayne: Haven't you ever considered trimming them? My friend did it and she looks prettier.
Aishah went on to explain about Islamic practices but Wayne did not appear to be receptive.
*Names have been changed to protect the privacy of the individuals.

It could be that Wayne was simply insensitive, but I believe that this is not an isolated case. Although people of different races get along pretty well nowadays, there is still a lack of sufficient knowledge about practices and beliefs of other cultures. As a result, we might unknowingly offend people around us.
That said, we should still be forgiving towards others, for only then will Singapore remain peaceful and harmonious.
