To understand something you have to rely on your own experience and culture. Does this mean it is impossible to have objective knowledge?

Experience is a group of events and incidents that a person goes through on a daily basis in his life, experience can be small or big; they can happen at home, school, work, countries.. etc. They can be individual, between two people or at group level. Some experiences can be small and hence have a small effect. People can forget these experiences. However, some experiences can be very strong in a way that effects peoples beliefs, ideas and attitudes towards issues. Moreover, the more that experience repeats the stronger the effect they have on how people feel about matters or view them. For example, experiences that people have in their childhood at home can affect their views towards marriage or divorce. Experiences that people gain at schools can affect how they view issues related to education, and schooling such as where to send their children to. Moreover, educational experiences can affect the kind of knowledge that people acquire: what knowledge to choose or adapt as well as how to acquire knowledge.

Normally, when experiences come from the culture where a person lives, they tend to be very rooted in people's beliefs and attitudes and can affect the objectivity of their views. People tend to take sides that are based on the kind of experiences that their cultures lived throughout the years and passed to their children one generation after another.
