What about the freedom of speech? Donald Trump has never instigated violence towards any particular minority ethnic group. He has only proposed to place restrictions upon Muslims and other immigrants entering the United States. A large section of the American population is concerned about the abrupt demographic changes caused by the unlimited immigration. They want this to stop.
Well his words can be interpreted like hate speech, I mean he's clearly crossing the line sometimes it's just a matter of opinion and many judges will rule his sentence different if that was the case. Openly mocking a disabled person is a crime in many countries already.
