In "Dark Continent" by M. Mazower, I read the following with regards to the 1920s:

In the first place, democracy’s international backers were less supportive as time passed. Woodrow Wilson’s legacy of messianic liberalism was undermined by American isolationism, while the European victors—Britain and France—were concerned more about communism than dictatorship; so long as the new states of central-eastern Europe held communism at bay, they cared little about their domestic political arrangements.

So already in the 1920s many European leaders were against communism. The text does not quite make it clear why this is so though. It does mention the following:

Yet the development of the Soviet system had a less immediate impact on the rest of Europe than seemed likely in 1918. The West’s intervention in the Russian Civil War failed to topple the communist regime. But equally across the rest of Europe, the much-feared revolution either failed to materialize, or was easily put down. Despite the wave of soviets, strikes, mutinies and insurrections which swept Europe in 1918–19 from Scotland to the Adriatic, with street fighting in Germany and a violent civil war in Finland, there was only one other country where a Bolshevik regime actually seized power for any length of time, and that was Hungary. As in Russia, civil war was the consequence; the outcome, however, was very different.

Given this limited impact of the Sovient system on the rest of Europe, I do not understand why people were so strongly against it from the start, while being more accepting of other dictatorial forms of government.
