The constitution says FREE SPEECH. You are for the constitution, right, luddly? Cuz if you don't, you are supposedly a right winger, right? So....why are you trying to shut people up when it is their RIGHT to state what they think/believe? I know why. You don't agree with it. Therefore....HUSH. amirite? Yep. iamrite.
You're wrong, as usual.
Free speech refers only to the relationship between the government and citizens, placing restrictions on government to seek to preempt or restrict the free expression of citizens.
It does not apply to the relationship of private persons in the context of a private venue such as an online message board, where it's perfectly appropriate to denounce the hate speech of racists, and for message board administrators to edit or delete speech determined offensive or inappropriate.
Private citizens in the context of private society, therefore, determine what is or is not appropriate speech, and set the rules and boundaries accordingly.
This, then, is the fundamental nature of a truly free and democratic society, where private citizens alone determine what is or isn't appropriate speech – absent unwarranted interference from politicians, bureaucrats, and the courts.
