They aren't hiding behind the door they are marching in the street, sieg heiling in some cases in Europe. Fascism didn't disappear in 1945, Oswald Moseley's Union Movement was active in the UK until the late 70s, when groups like the National Front became more prominent eventually developing into the BNP, who eventually splintered into groups like Britain First, the fringes of UKIP, the EDL etc. There are similar stories across Europe and there are groups in the US inspired by these movements and worse with several active neo-nazi groups currently operating. To pretend they don't exist, and have played no role in far right mobilisations here and abroad is either deliberate dishonesty or willful ignorance.
Or just realism. There are a lot of people who clothe themselves in the imagery of fascism, knowing that it is powerful and offensive. There are some people who actually identify as fascism in a meaningful way, but they are a tiny, tiny number of people, and have no significant role in modern society. The fact that Oswald Mosely was still alive in the 1970s, trying to push his fascist dreams does not mean that fascism had any real hold in Britain at the time. And there is certainly no fascist conspiracy, trying to infiltrate modern society.
Meanwhile, there are, of course, plenty of people openly espousing the following principles:
- Opposition to democracy
- Racial essentialism
- Antisemitism
- Promotion of censorship
- Approval of violence as a political tool
They generally go by names such as "Momentum" or "antifa" or the like, and they love the notion of an ever present fascist threat, as it justifies many of their antisocial activities.
