Simple rules. You move to a country, yuo live by that countries rules, traditions, conditions, etc. You dont come to another country and try force your beliefs, way of life and whatever else on the people of that country. If they want to know how you do things, im sure they will ask.
Situations that annoy me especially are those with schools bending rules for foreign students. Being allowed to wear the muslim headscarfe, being allowed to carry a small knife, not saying god bless in some schools as it may offend them. Im damn sure if aussie kids went and lived in the middle east for example, they couldnt turn up at a school there in a skirt, their head uncovered and wear a cross around their neck (yes I know im generalising, but you get the point). You adjust to the way of life of the country you move into. If you dont like it or its offensive to you, then head back home.
Also, if you come here, make an effort to learn english. Mix with people other than that of your own nationality. No offense to anyone here but the chinese tend to be really bad with this at times.
