Statism, being generally a belief in the necessity of government, may not appear to exactly resemble a social movement. It does not have grassroots organization, but I still think it can aptly be described as a movement.
“A social movement is a type of group action that seeks to achieve or resist societal change.”
This has to do with liberty because people are educated to believe government is necessary, and some end up promoting idiotic ideas. As long as a majority of people in a given geographical place use these mistaken ideas to advance their unjust causes, we suffer.
