Of course fascism is real, just like communism is real. The term fascism is often used either a) totally wrongly or b) hysterically. In the same way right-wing people may yell woke at things they don't like.
If you think Farage is a fascist that's fine, but in my view it's wrong. The way people band about the term fascism is disrespectful in my view to people who know what real fascism is.
It's the reason people will proudly declare themselves a socialist, they've never lived under it in places like Venezuela, East Germany, Romania or Yugoslavia.
It wasn't real socialism though, obviously.
