What is revolution?

Is joining a group in Facebook a sign of something happening in reality? Does joining a group in virtual reality mean something other than a push of a button, labeling one’s identity in public and among a group? What kind of reality is in social media other than minds and senses put together and how do things done in social media reflect what is going on socially in the concrete world? Should we even not make a difference between virtual and bodily concretion? Between people happen things we call social interaction, communication, conversation, deeds, makings and social activity, a mixture of events and thoughts. Social media and making revolutions with help of internet provided platforms can give a strange feeling of accomplishment and progress. How many people, hundreds of thousands, tens of thousands who like, who comment, who pass and share messages, who inform and make. This information space and how it functions clearly affects our reality and lives in the world in a massive way. What is revolution in this and importantly when people desire to accomplish revolution using social media what happens other than togetherness and same-mindedness in virtual reality?
Social media is much about liking and feeling good, sharing the fun one is having. Activism can cleverly join in the fun and make way for social media to be part of change. It is of course possible to ignore socially important issues and pay attention to oneself only, be as blind in social media as in everyday normalcy. As someone asked me at the university when I talked about being an activist in social media like Facebook: How is it possible? What is activism in Facebook? For many it is still a new thing and I feel I am talking to a wall.
My question what is revolution is demanding. Revolution is and must be aggressive. To point out my aggression and rage are not to harm or kill in the traditional way, but to make a turnover of minds, of how things are done. Revolution means in my world a complete change. It is not marketable, nice, flattering nor pretty. Those who think you can get the shells of revolution but not the contents are wrong. That is not how it goes.
