By some measures... yes? Take slavery, which would be considered even more right wing than whatever the current US "far right" is, but was more or less tolerated before abolition. Does that make all parties of the time far right?
A popularity in election results doesn't define a parties position on the political spectrum. A lot of people are voting for change to occur, but that doesn't mean that that change already happened just by counting the votes.
What? Slavery wasn't tolerated. It was celebrated(still is) in a large amount of the country. It was considered a right by many white people in the US. Something they were entitled to(entitlement is a big theme with American conservatives) and still are.
Let's not forget, or maybe let's try to learn, that racism was the united states original social/cultural export. Back in the day Americans were seen as the most racist people on the planet and they were proud of it. Americans minstrel shows were big business and a very early one in the countries history.
Let's not forget that well after slavery was outlawed, Americans were still firebombing black/indigenous neighborhoods, towns, and lynching people. Americans still kill native Americans to this day, lookup native American women going missing.
Let's not forget that Kanye, just a few years ago, said that slaves had it good and should have been thankful. While that was absolutely the ramblings of a mentally unwell person, he was simply restating what is prevalent in many circles in America today. Kanye was just repeating what was said around him and is repeated in "private" across much of the country.
Lol wtf ya think ICE actually is? It's just a government force meant to remove the blacks/browns/foreigners who take all the good jerbs from the hard working whites.
