Fascism historically has been a mix of left and right wing policies
and we see that in the current fascist wave
Certainly some people are xenophobic just because that's how they are
Some have been fed lies or have had fears professionally whipped up about certain groups
Others are anti-immigration because of deprivation, which they fear more mouths to feed will worsen
Some are just attracted by promises of bringing back industry or spending more on public services, just the hope of a less shit life
It isn't possible to extract xenophobia from someone's head,
but we can do a lot to remove the attraction of the promises of more jobs, better working conditions, rebuilding public services etc
Education is important too:
Many people were never properly taught about the Holocaust, or about what people suffered in other fascist states like Spain,Portugal, Greece, Argentina ...
or weren't listening / attending at school.
The idiocy of some on the left equating Nazis with Israel, or with saying women don't have penises,
is that fascism has lost its horror.
We need to remind all of Europe of the crimes that fascists & Nazis committed in the past
So the ignoramuses no longer think it cool to give Nazi salutes and cheer the names of past fascist leaders.
