Banning a subsect of people from the country counts as hate speech.
It is not a hate-speech. It is just a precautionary measure. Do the Americans allow North Koreans to travel to their country? No. Every now and then, the Americans deny visa to high ranking politicians from around the world. A few years ago, the current Indian prime minister (Narendra Modi) was denied a visa to visit the United States.
There is a difference.
Muslims represent 1/7 people across the world and actually have a lower chance of being a terrorist than White Americans. North Koreans are banned from entering the country not because of fears of terrorist attacks but instead to limit their technology and economical power as a punishment for their aggression. If Donald Trump wanted to ban ISIS members from entering it would be one thing. But banning 1/7 people for something that causes no more terrorism than Christianity is just silly.
