Fascism is a political phenomenon of the early twentieth century. There are no current politicians who are operating in the early twentieth century. So, to speak of “currently active fascists” is anachronistic. Typically at some point in the discussion someone will cite Umberto Eco’s definition of fascism, but other people do not have to accept his extension of the term past its sell-by date.

For the people currently active in politics who espouse heinous policies sometimes (and sometimes not) reminiscent of fascism, then advocate against those policies directly. Using such a vague umbrella term, and one interpreted by many as a distinct cultural shibboleth, isn’t likely to win over the people you need in order to prevail.

With that line of thinking, you can attribute any ideology to a time period and declare it invalid today.

Professor Jason Stanley who has written two books about the topic calls the current US administration fascist. Similar with professor Timothy Snyder and I think several other respected historians.
