Record number of threats against MPs reported to federal police in Australia

Yes. That tends to Hpplen when you become a totalitarian state.

Yet in the US, there were more than 9,600 recorded threats against members of Congress in 2021...

But the population of the US is nearly 13 times higher.

Is that more or less than usual? Congress in the US hit single digit approval ratings at one point last year.

And with your statement of the US congress being single digit at one point last year, the lowest the congress approval rating ever reached in 2022 was 16% which was back in June 2022. Yet the last time the US had its congress at single digits was November 2013 which was at 9% when Obama was president.

Updated because I miscalculated...

I wasn't surprised the US had a high amount of threats against member of congress considering the fascist population of the US is much higher than Australia.

A total of 46% of the Republican supporters are Faith and Flag, and Populist which have links to Far-Right movements.

With 28% of Americans are Republican, Calculating 28% ÷ 100 x 46%, that would mean that 12.88% of Americans are fascist or leaning towards Fascism

Meanwhile Australia has far less of a fascist problem with only 5% of Australians voting for One Nation and some of the 4.1% of UAP voters being fascist.

I reckon its only 1,000,000 Australians who are Far-Right compared to more than 42,000,000 American Fascists.

No sorry. Being Fath and Flag and Populist has nothing to do with Fascism or Alt-Right movements like the skin heads or Nazi's (which are really far left with total government control). Having a religion and believing your country is good does not equal fascism.
Your premise is wrong. Also use per capita. The populations in these countries are vastly different.

Maybe so, but look at this data I have found... at least 20% of GOP members of Faith and Flag and Populist are indeed related to Fascism or even Neo-Fascism

You don't seem to understand what "very conservative" means. It doesn't mean neo nazi fascist. It means they conserve traditional Christian values, which doesn't care one bit about race.

Some are fascist some are just plain right wingers like Ben Shapiro who is a critic of the alt-right.

While we're at it, there was a study saying that 24 million Americans have Alt-Right beliefs, and that was back in 2018. It'll probably be much higher the Alt-Right population

But still, 24 million is a whole lot higher than 1 million, and 24 million Alt-Right Americans is nearly just as high as the entire Australian population

Crikey indeed, a record that an average Australian doesn't want to hear but have to know about
