Not to rip off @quinnae.com's book, but: Change is made by movements of people fighting for or against something. It will probably not be accomplished by posting. It is in the interest of social media sites -- even this one! -- to make you think nothing can be changed, so you keep on posting.
One function of social media is to leave you permanently frozen in a state of "things can only get worse." This is not to say things can't -- and possibly will -- get worse. It is to say that nothing is inevitable, and we all have a role in creating the future, no matter how powerless we feel.
