To compare steemit to FB is a kind of nonsense and mendacious. Steemit is for bloggers who can earn money for their content. FB doesn't pay you, and neither is it a blogging site. I agree with what you are saying about freedom of expression. Although I don't like some of the stuff being posted on steemit, I defend their right to say it, so long as it's within the boundaries of decency and doesn't spread hate etc. After all, that's democracy!
