Next to the man himself (President Trump), trump supporters are probably the most despised group of people in the United States, which includes an estimated 50% of the US population. They are despised by the left leaning individuals and illegal Mexican immigrants. Liberalism stands for peace, and the tolerance, but their behavior was shown anything but.
Tolerance does not include attacking individuals for having different beliefs than you, whether verbally or physically (which we have seen often). It does not include making threats of physical harm to individuals for holding political beliefs. Tolerance is also not belittle others who hold a different opinion than you. Political views aside, hypocrisy is a terrible, terrible thing.
