Why leftists, particularly in America, considered far-right political figures as neo-nazi?

It's called liberalism, the belief in equality and human rights being protected. The argument is that the right-wing is more concerned with liberalism because the issues of gay marriage, guns, climate change, abortion, and state healthcare are a threat to their individual freedom. Liberals don't seem like liberals and more like Nazis.

Liberals hope that the majority don't remember that the Nazis were socialists. Also not publicized is the fact that Mussolini described facism as their version of the New Deal.
