Before attaining dictatorial power Hitler allied himself with political conservatives,... Would that include conservatives like FDR and his Brain Trust?
Father Charles Coughlin until 1936 was a strong supporter of FDR. https://encyclopedia.ushmm.org/content/en/article/charles-e-coughlin
"National Union for Social Justice
In 1935, Coughlin created the National Union for Social Justice (NUSJ) as a political action group that would represent the interests of his listeners in Washington, DC. By the 1936 presidential election the NUSJ had over one million paying members.
In 1936, Coughlin founded a journal entitled Social Justice, providing another venue to promote his populist ideology. The NUSJ tabled 16 principles as guidelines for their program for the United States. These included:
liberty of conscience and education;
nationalization of resources too important to be held by individuals;
abolition of the Federal Reserve Board;
return to Congress the right to coin and regulate money;
rights of workers to organize unions;
requisition of wealth and conscription of men in times of war;
and the principle that human rights should outweigh property rights.
Coughlin was ahead of his time in splitting his ticket and supporting issues associated with the left (such as federal support to prop up the dollar), and issues associated with the right (“America First” foreign policy).
Over the years Coughlin had managed to keep his antisemitism muted while he was on the air. After his split with Roosevelt and with the rise of National Socialism and Fascism in Europe, however, he attacked Jews explicitly in his broadcasts. Some historians attribute this change to Coughlin taking advantage of rising antisemitism around the world in order to keep himself relevant. Based on his speeches, writings, and associations, however, he appears to have had significant antisemitic sentiment throughout his career.
For years, Coughlin had publicly derided “international bankers,” a phrase that most of his listeners understood to mean Jewish bankers. In the days and weeks after Kristallnacht, Coughlin defended the state-sponsored violence of the Nazi regime, arguing that Kristallnacht was justified as retaliation for Jewish persecution of Christians. He explained to his listeners on November 20, 1938 that the “communistic government of Russia,” “the Lenins and Trotskys…atheistic Jews and Gentiles” had murdered more than 20 million Christians and had stolen “40 billion [dollars]…of Christian property.”
In a series of articles published in Social Justice during 1938, Coughlin lambasted “Jewish” financiers and their control over world politics, culminating with a story recounting his own version of the infamous 20th Century forgery, the Protocols of the Elders of Zion, which purported to be minutes of meetings of Jewish leaders as they plotted to take over the world."
Now days are social justice workers left or right wingers? They are and always have been left wingers.https://www.pachamama.org/social-justice/what-is-social-justice
