Dictatorship exists in all countries but with different tactics! They only care for personal short term profits & do anything to reach their goals even by fooling simple-minded people, hiding the truth, manipulating science & everything, putting public mental & physical health at risk, abusing non-human animals, polluting environment, destroying family values, promoting materialism & sexual degeneration in the name of freedom,….. & turning people into programmed robots! “Make the lie big, Make it simple, Keep saying it, And eventually they will believe it” Adolf Hitler… There is no free speech in real world & you will be suppressed for telling the truth that is not supported by the system. Videos of targeted users are filtered & merely relegated, so that people can hardly see their videos! There is no equal growth opportunity on YOUTUBE or any other video sharing site, your channel will grow if they want to!!!!!"Aghdam's brother warned authorities in advance after she stopped responding to phone calls over the weekend, according to CNN.Her complaints also were posted on a separate website the San Bruno Police Department is investigating. Despite Aghdam voicing concern over YouTube's updated advertising policy and lack of free speech, a motive remains unclear, authorities said.
