To describe 1940s US/UK as 'antifa' is ahistorical.
Until Nazis threatened UK/US imperial and economic power, they did nothing to challenge them other than ask them to stop invading neighbouring (ie white) countries.

Both countries only suppressed domestic fascism after joining ww2, not out of any moral or political objection to its principles, but to avoid a fifth column (internal saboteurs) undermining the war effort.

Championing the architect of the Bengal famine who sent black and tans to NI to massacre civilians (Churchill) or a president who rounded up 120,000 japanese-americans into concentration camps & quashed anti-lynching laws to appease southern democrats (FDR) as "antifa" is wild.

America's Jim Crow laws didn't just inspire the racialised segregation in Nazi Germany, but actually went further than they were willing to go.

During this era there was a genuine anti-fascist movement, but it was civilians who took to the street to oppose the rise of fascism and were often confronted by the state for doing so.

1936, Cable St, London, Police were sent to protect a March by the BUF (British Union of Fascists). Despite being attacked by police, a loose coalition of anarchists, communists, jewish immigrant communities, irish dockworkers & trade unionists managed to get the march disbanded.

Here's a picture of the leader of the British Union of Fascists Oswald Moseley being punched to the ground in Manchester in 1933. It's a reward for reading so far.

At the same time in America, the story is different but connected. There are huge protests & conflicts labelled "race riots", often sparked by violence against the black community by white police. These protests are met with extreme force by the state. Any of this sound familiar?

For Black America, there is no "emerging fascism". They already live under a racist authoritarian regime. This is not an opposition to the creeping legitimacy of fascist ideals, they are fighting for their lives. Then and now.

These struggles are politically and historically connected but should not be conflated. Not by reactionaries attempting to find an 'outsider agitator' to ignore the legitimate grievances of black americans.

Nor by commentators attempting to appropriate struggles and protest of people of colour to launder the reputation of imperialists states who to this very day support racist authoritarian regimes abroad.

We’re going to hear more & more discussion and myths about antifa in the coming weeks. But 'antifa' did not start these protests, it was black communities opposing racialised policing. Black voices, organisers and communities are and must remain at the centre of this movement.
