So, first, if you go mainly by the wiki page, then the definition of fascism states it is purely a right wing system. However, if you go by the actual dictionary definition, aka, the definition, it is:
1: often capitalized
: a political philosophy, movement, or regime (such as that of the Fascisti) that exalts nation and often race above the individual and that stands for a centralized
autocratic government headed by a
dictatorialleader, severe economic and social regimentation, and forcible suppression of opposition
2
: a tendency toward or actual exercise of strong autocratic or dictatorial control
Nothing specifically stating "right wing".
So let us take the definition and see what ANTIFA and the far left in general want.
First, race above the individual. So.... things like affirmative action? This puts race above the individual. Identity politics where race is how people define themselves? Race above the individual. The far left puts race above all else in almost all of its politics and social issues. Even down to simple stuff like entertainment.
This is purely anecdotal, but I've watched Colbert (basically the most left wing late night host there is) and many times his audience cheers in odd places. For example He spoke about the next 007 being a black woman. Before the audience knew who the actress was they cheered just for the character being a black woman. The actress did not matter, just the race and gender. When Hillary ran for president all we heard was "It's time for a woman president". Basically saying we should vote for Hillary because she is a woman. AOC won with no experience or knowledge of basic policy. She won because she was young, Hispanic, and a woman. How many times have we heard the left say they don't want any more old white men telling them what to do? The left LOVES to put race, gender, and sexuality above the individual.
Second, standing for a centralized autocratic government. So... which party wants a strong government that has control over almost all aspects of life? The right that wants to decentralize and privatize things, or the left that wants the government to control healthcare, schools, provide basic income, etc? The left loves big government and the far left wants to do away with privatization in most aspects. They detest businesses as a whole. The left wants the government to control everything just not a republican government. They want an autocracy of liberals. Had Obama said he wasn't giving up the presidency, they would have cheered.
Third, severe economic and social regimentation. So... which party is the one trying to control language and ideas? Which is the one that wants severe regulation of private businesses? Which is the one trying to dictate what behavior is and is not to be tolerated? The far left has become insanely concerned with controlling social behavior. The far left ahs invented an infinite amount of genders and pronouns that we all need to recognize. The left has passed laws that control speech and may cause you to be fined if you "misgender" someone in a place of business. They are the party that jails people in the UK for "hate speech" which is determined by the state with no clear definition.
And finally, forcible suppression of opposition. This is all ANTIFA does. They try to shout people down or beat them into submission. If someone says something they don't like, they attack. They dox, they try to eliminate right wing YouTube channels and have right wing twitter accounts taken down. They want the removal of ideas they disagree with. Almost all media is left wing. So.... which party is trying to suppress the opposition again?
And this is why I can not process what you said. It was so crazy that it made my head spin. They act like fascists because they use fascist tactics and want a fascist liberal government. The fight against the current government which also exhibits fascist tendencies. ANTIFA is a left wing fascist group that claims to fight fascism from the right.
If it walks like a duck, and talks like a duck, it's a fascist,
That's my response. I hope it was everything you wanted it to be.
