The point is censorship. Vandalizing somebody property is not free speech, it is against the law. Saying I hate whites, of blacks or liberals or conservative or any other group, is free speech. If I walk into a black bar and spout the KKK mantra, I will probably get my butt kicked but I won't got to jail. When the voice of the people is silenced by censorship, not matter if it is for or against your political views, you have lost an irreplaceable constitutional right. Freedom of speech is the first Freedom to be stolen by government so they can steal the next constitutional right, to bear arms. Once the the public has been silenced and then disarmed, the government can and will do what every it wants, regardless of any moral or legal laws. Nobody will hear about these violation or be able to resist those in power. Yes, people must be accountable for their action but that accountability is not the result of censorship, just the opposite.
What would Dr. King or Gandhi have accomplished if they and been cast as hate mongers and all their work was censored and so nobody would know what they were trying to accomplish. You silence the opposition, not for the good of all but just for your own good. When you can't defend your position, then you censor the opposing opinion. Just another form of BOOK BURNING.
