According to culture is a population of memes which are just "copy me" programs

According to Richard Dawkins, culture is a population of memes which are just "copy me" programs.

Just as genes reproducing themselves, memes are actions, behaviors, units of culture that are replicated through language or observation. 
This way of describing culture has some important ramifications:
first, culture is not a way of thinking that a certain population share, but in opposition is something we have in common with people with our same culture; 
second, where an individual experiment some degree of conflict between the cultural norms and its belief, this conflict is not caused by an external force but instead is a conflict that is taking place in their heads;
third, if you view culture as a similarity between people, like brown hair, it is much easier to remember that perspective matters;
lastly, this way of viewing culture gives us a measurable way of thinking about how culture is spread among different individuals.
