Fascism and communism were both the epitome of totalitarianism and authoritarianism. Which do you think is worse? The authoritarianism of their rule could be one your reasons, but the ideas and policies that aren't necessarily related to totalitarianism can and should be taken into account.
For the sake of this poll, Nazism is considered part of Fascism.
Ideologically speaking, I'm more opposed to fascism and have more sympathy for communism.
When communism gets talked about, it's all too easy to focus on Stalin and Mao, as they were the leaders of communist nations, the USSR and the People's Republic of China.
But it's important to remember that there were a lot of individual communists who were so because they were seeking power or because they wanted to be authoritarian. Rather, they were communist because they believed that Marx was right in many of the ideals of class conflict that Marx brought to light in his writings.
There have been a lot of communists who were so because they wanted greater racial equality, greater gender equality, safer working conditions, better living conditions, and improvement of quality of life for as many people as possible.
In fact, (and this is mentioned little in her biographies when we learn about her in school) while Helen Keller was an advocate for the disabled, she was also a socialist who lobbied to end all the reasons why people became disabled in the first place.
And when United States President Dwight D. Eisenhower uses his farewell address to warn the American people about consumerism as well as the military-industrial-congressional complex, I think it's easier to understand communist rhetoric about how wars between nations are fought by the poor of the world so that the businessmen of the world may profit.
So, ideologically speaking, communism is a philosophy of inclusion and it seeks to use break the traditional barriers - gender discrimination, racial discrimination, physical disabilities - that groups have used to oppress each other.
Now let's take a look at fascism.
Fascism is uses nationalist dogma to unite a group of people under a leader of the state. The appeal of fascism is that the whole nation can be directed by its leader to pursue singular goals without opposition and attain them.
The problem I have with fascism is that it is a philosophy of exclusion. Because of the nationalist doctrines fascism espouses, it excludes the ideas and discoveries that other nations think up. It even excludes new thinking from within itself. Because of this, fascist countries are unable to adapt quickly when its leaders are opposed to the changes that must be adapted to.
Also, while communist ideology is revolution from the bottom-up, fascist ideology is revolution from the top-down. Fascism, by its very ideology, holds that a small group of people should have power over a larger group of people, usually justified by racial superiority but nowadays may be justified by economic superiority - that is that the wealthy deserve to run things because they have wealth.
But the problem with that thinking is that not all wealth is created by virtuous means, or by means that a businessperson controls. A person of wealth can be utterly inept but that doesn't mean anything if his property has gold or oil underneath it. That wealth is from the land - not from the competence of the landowner.
So, ideologically speaking, I am more opposed to fascism.
