wow…
First of all, liberal means dynamic and conservative means static.
Now that we got that out of the way…
Radical is an extreme liberal.
Reactionary is an extreme conservative.
Let’s go a bit further…
Socialism and Communism are not the same. Calling Karl Marx a socialist is a bit like calling Stalin “a bad guy”. Marx was a radical. The idea of revolution (which is a large part on which commuinsm is founded) is radical. Being socialist is liberal, but not radical. The United States has many socialist ideals. In fact, the very concept of taxation is a socialist ideal. People tend to put a negative stigmatism on socialism because of the communist uprisings of the twentieth century. Socialism is not evil. In fact, a perfect government is a perfect blend of socialism and free enterprise.
Next step: When talking about coservatives and liberals, there are basically two different agendas that need to be classified: economic issues and moral issues.
When it comes to economic issues, the liberal side of the fence is, of course, the side that favors government aid. The more government aid that is rendered, the closer we become to socialism. The less government aid that is rendered, the closer we become to a completely free economy where monopolies rule. These monopolies are generally called government utilities because, after a time of free enterprise, the government either gives power to these monopolies or it loses its powers to these monopolies. The most such powerful monopolies are either the military monopolies that existed in the middle part of the twentieth century in Europe or the religious monopolies that existed in during medieval times in Europe.
When it comes to moral issues, liberals are generally in favor of a lack of government intervention while conservatives are in favor of dictating morality to the public. The pure liberal side of this fence generally leads to either anarchy or a situation where the government doesn’t dictate morality at all and may actually destroy institutions that preach morality (religion). Of course, the end result is a policy of order through scare tactics where the only morality is “loyalty to the state”. The pure conservative side of this fence generally leads to a situation where the government becomes the all powerful force in a citizens life. Concepts like “motherland” and “homeland” generally arise from a very conservative point of view.
One can see that there is truly little difference between pure reactionary and pure radical, hence, the confusion in definitions. The difference is what it takes to achieve those extremes.
Hence, given the above examples, extreme liberal (radical) equals communist while extreme conserative (reactionary) equals fascist.
Right smack dab in the middle is democracy.
