From what I've read, anti-semitism, while it existed, wasn't mainstream in Germany as well. But the Nazis were "Peaceful Racists" at first (they changed pretty quickly) and seized power. I genuinely fear the same might happen in the US ...
For example, you might be surprised to learn that the Democratic party was the party of slavery in the South and that the Nazi party used the Jim Crow laws as inspiration for their racist segregation and treatment of Jews. As shocking as this statement sounds, the Nazi party shares its ideological roots with the Democratic party. If you don't believe me please fact check it.
Lastly, I'd recommend reading Thomas Sowell and Dinesh D’Souza for a better understanding of what is conservatism.
So who is being dishonest?
Let's drop the sham that not all conservatives will go down the terrible path of Nazism/White Supremacy in this current political climate. If not a certainty, from how Trump has been able to get away with one amazingly blatant political scandal after another, it shows just how its terrifyingly possible for that to happen. There is a path from A to B, and to ignore it is dangerous, disingenuous and dishonest
I'm talking about western values: private property, freedom of speech, the right to live.
These are historically conservative causes. These are judeo-christian values. How can a conservative be a Jew-hating Nazi while at the same time defending their values? It's a contradiction, it makes no sense.
In fact it's the left that is pretty much anti-Israel and pro-Palestine (like Hitler btw).
The Nazis first attacked and destroyed the free press and other free-speech institutions. Robust legal protections for free speech, and a culture of vigorously defending it, will prevent tyrants from gaining and maintaining power.
There is no 'paradox of tolerance'. The intolerant are intolerant, no matter which side they are on. Peaceful racists should have their say. We are all free to disagree and shun them. This isn't ivory tower. This is part and parcel of a free and open society.
