How culture affects my communication

Your culture is actually your way of life, how you do things, customs, mores, traditions, beliefs, laws and more so guidelines on one's behaviour. By its definition alone one should be able to understand why culture can influence certain behaviours and affect communication, but sometimes, we forget that their are co-cultures within a dominant culture and this changes things a lot. A dominant culture is a shared system of beliefs by the masses. It is a general understanding of how things work around there, but a co-culture is a group within a dominant culture who operate differently.
I am a Trinidadian and in our culture people generally dress however they please when in a social atmosphere, eat various types of food and meat, listen to different genres of music, etcetera. However, I belong to a co-culture with that dominant culture, that is, the Rastafarian community. More specifically I am belong to the 12 Tribes of Israel which is a sub-culture of that culture, one would say. Now within this culture (12 Tribes) females are not allowed to wear pants, generally we listen to reggae music and we eat the meats the Bible spoke of in the Old Testament. The way we greet each other is different to the way the dominant culture greets one another. Whereas one might say "Hello, good morning..." we usually say "Greetings" to which the same is replied or we say "Rastafari" to which "Selassie I" is the reply.
Now we are not ethnocentric because we believe that other culture too will also enter into the kingdom of God. We do hold ourselves in high esteem because we belief that we are prince and princesses out of Africa. Some might find us proud and that we are but we are humble in that give Jah glory and not ourselves! This makes us think a certain way and behave a certain way which in itself is communication. I wear mostly skirts (only pants when hiking or on field trips with my students) and I speak and think a certain way because of my beliefs. Certain body languages I do may only be interpreted by other Rastafarians and the things I say may only make sense to Rastafarians but generally because I am part of a dominant culture I reflect those things are are common with my co-culture.
