By failing to prosecute hate speech, the US is explicitly and flippantly violating international human rights law. No other country would be allowed to get away with this, so why would the US? The United Nations has stated many times that international law has absolute authority. This is quite simply not optional. The US is required to outlaw hate speech.
Attention, Miss Cohen:
Bullshit. The highest law of the land in the US is the Constitution, not the 'international law', demands, or requirements of that tyrant-infested collection of liars and thieves known as the United Nations.
Also, your demands for an end to hate speech sound hollow when you, over and over, call the entire United States racist, misogynist, and every other word-as-club clowns like you use to try to beat people into obedience. That's some serious hate speech coming from someone demanding an end to hate speech.
Therefore, I suggest you take your intolerance, your bigotry, and your hatred of this country, fold it all to eight corners, and shove it up your ass.
