You don't have to hate a certain race to be fascist. It's just putting your nation above all others (even at the other countries detriment), while also being violently authoritative to your opposition and people. Taking control of business, banks, and religion. Antifa may not be about putting America above all other countries, but they sure as hell check off all the other qualifications.

That's not fascism. 

"Fascism is a form of radical authoritarian ultranationalism, characterized by dictatorial power, forcible suppression of opposition and control of industry and commerce"

Considering that antifa likes communism, socialism and anarchism, it makes sense they act the way they do. 

"Opposed to liberalism, Marxism and anarchism, fascism is usually placed on the far-right within the traditional left–right spectrum."

https://en.wikipedia.org/wiki/Fascism

"Since the emergence of fascism in Europe in the first half of the 20th century, the term "fascist" has frequently been used as a pejorative epithet against a wide range of individuals, political movements, governments, public and private institutions, including those that would not usually be classified as fascist in mainstream political science. It usually serves as an emotionally loaded substitute for authoritarian."

we should use the scientific definition of Fascism because otherwise the term becomes pretty meaningless. So the Antifa is not a fascist group.

Every moderate leftist person shouldn't sympathize with the Antifa, they are extremists and their goals don't justify their actions. Furthermore, the Antifa might not be the worst scum but always pointing out that there is even bigger scum, is downplaying their actions.

We just gave you the actual definition of a fascist.  From the exact same source you posted.  Now, just because some like to (falsely) equate fascists with the far-right, doesn't make us incorrect.  Fascism exists on both sides of the political spectrum.  In fact, while many on the Left don't like to admit it, it is mainly what the Communist/Marxist countries become.  Because you can't have a country completely controlled by the government when man's natural instinct is to remain free, so you must do so by violent force, all the while preaching about it being the best for the motherland.
