Anarchism is not a diverse ideology that includes all viewpoints. It is against the state, the market, and other forms of oppression. It's ultimate goal is a society free from oppression.
Many people coming to anarchism seem to confuse personal freedom with individualism. Personal freedom is what anarchism promotes, individualism is a form of oppression that blames the victim for their failures. Anarchism promotes autonomy, self contained units, communities, and collectives, that make decisions together for the group. A person is ineffective alone as an individual.
An anarchist society could potentially include most forms of cultural variation including those that are not anarchist cultures. For example, a market culture could exist, as long as it doesn't lay claim to all of nature, and respects cultures that do not recognize private property. Of course, this example renders the market culture ineffective at supporting itself, since it needs exponential growth and exploitation of resources to survive. However, theoretically it could coexist with other cultures.
Anarchist culture does not include oppressive organizational systems like market economies or insisting on a single subjective or objective reality. The economy of Anarchism is called mutual aid. Essentially it is a gift economy, It is the economy of nature. Cooperation is favored, competition is reduced or eliminated. People who share and help others are respected, people who act in self interest are not.
There are many organizations that receive funding specifically to disrupt anarchist communities and cultures. It is a way to keep anarchists fighting among themselves and hindering them from organizing into stable communities. Divide and conquer. Some of these forms of disruption focus on individualism and try to include markets in their literature and messaging.
Keeping anarchists from organizing, forces them to rely on individualism of the market. It disrupts the formation of alternative cultures, and limits emerging cultures to the market based subcultures that exists today.
Anarchism is not an identity, it is a way of life. Just because someone identifies as an anarchist, does not mean they understand what anarchism means, or how it exists in the world. In turn most anarchists would never call themselves an anarchist, either because they reject the label which hinders their movement in the world, or they are unaware of the collection of concepts and practices that are anarchism.
There is too much disinformation in the realm of anarchism to make sound judgements.
