Subcultures Subcultures Anarchists Anarchists will be prevalent in the future as they are today. Some have a misguided ideal that government is inherently evil and people can live without government. Others are just nuts who are looking for an excuse to kill people. They will destroy arcologies, attack governments and corporations. Generally anarchists will claim that they want to return to a farming or a hunter-gatherer society.
Problem is, there's too many people to do that with.
The greens love the environment. Nothing matters but the environment. If properly provoked, they will take up arms to destroy companies that are not friendly to the environment. If the corporations have bought off the government, it is even more plausible for them to take up arms, because the government is not going to listen to them. Some groups are peaceful, Amish types who practice what they preach.
