Do you think that marriage should be between a man and woman? OK, then do not say it openly in Facebook, cause you may risk being censored by some bureaucratic clerk watching your butt closely around the clock.
What is really amazing is the fact that Facebook is based in USA — not in Iran or North Korea! And they call themselves “liberals”: but, you see, the word “liberal” derives from the Latin word “liber” which means “freedom”. Then, how could a “liberal” be against freedom of speech?!
